VariantEval is overly abusive of the GATKReport (lack of) spec.
1. It converts numeric values (longs, integers and doubles) to string before sending to the Report, then expects it to decipher that those were actually numbers.
2. Worse, the stratification modules somehow instead of sending the actual values to the report table, sends a string with the value "unknown" and then abuses the GATKReport spec to convert those "unknown" placeholder values with numbers. Then again, it expects the report to know those are numbers, not strings.
Now that the GATKReport HAS specs, VariantEval needs to be overhauled to conform with that. In the meantime, I have added special ad-hoc treatment to these wrong contracts. It works, and the integration tests all passed without changing any MD5's, but right after Mark and Ryan commit their VariantEval refactors, I will step in to change the way it interacts with the GATKReport, so we can clean up the GATKReport.
No wonder, the printing needed to be O(n^2).
* when gathering, be aware that some keys will be missing from some tables.
* when a gatktable has no elements, it should still output the header so we know it had no records
- The Integer column type now accepts byte and shorts
- Updated Unit Tests and added a new testParse() test

* restructured the hash tables into one class (RecalibrationReport) that has all the functionality for the different tables and key managers
* optmized empirical qual calculation when merging recalibration reports
* centralized the quality score quantization functionalities
* unified the creating/loading of all the key manager/hash table structures.
* added unit tests for the gatherer (disabled because gatk report needs to be sorted for automated testing)
* added integration tests for BQSR and on-the-fly recalibration
-- Minor refactoring of state key iteration in VEW.map to make the dependencies more clear
-- Long discussion about the performance problems with StateKey, and how to fix it, which I have run out of time to address before ESP meeting.
-- The previous approach (requiring > 5 copies among all reads) is breaking down in many samples (>1000) just from sequencing errors.
-- This breakdown is producing spurious clustered indels (lots of these!) around real common indels
-- The new approach requires >X% of reads in a sample to carry an indel of any type (no allele matching) to be including in the counting towards 5. This actually makes sense in that if you have enough data we expect most reads to have the indel, but the allele might be wrong because of alignment, etc. If you have very few reads, then the threshold is crossed with any indel containing read, and it's counted.
-- As far as I can tell this is the right thing to do in general. We'll make another call set in ESP and see how it works at scale.
-- Added integration tests to ensure that the system is behaving as I expect on the site I developed the code on from ESP
-- StateKey no longer extends TreeMap. It's now a final immutable data structure that caches it's toString and hashcode values. TODO optimizations to entirely remove the TreeMap and just store the HashMap for performance and use the tree for the sorted tostring function.
-- NewEvaluationContext has a method makeStateKey() that contains all of the functionality that once was spread around VEUtils
-- AnalysisModuleScanner uses an annotationCache to speed up the reflections getAnnotations() call when invoked over and over on the same objects. Still expensive to convert each field to a string for the cache, but the only way around that is a complete refactoring of the toTransversalDone of VE
-- VariantEvaluator base class has a cached getSimpleName() function
-- VEUtils: general cleanup due to refactoring of StateKey
-- VEWalker: much better iteration of map data structures. If you need access to iterate over all key/value pairs use the Map.Entry construct with entrySet. This is far better than iterating over the keys and calling get() on each key.
-- Now the only use for update0, calculating the number of processed loci, is centrally tracked in the walker itself not the evaluations.
-- This allows us to avoid calling update0 are every genomic base in 100ks of evaluates when there are a lot of stratifications.
-- No need to modify the integration tests, this optimization doesn't change the result of the calculation
* added empirical quality counts to allow quantization during on-the-fly recalibration to any level
* added number of observations and errors to all tables to enable plotting of all covariates
* restructured BQSR to report recalibrated tables.
* implemented empirical quality calculation to the BQSR stage (instead of on-the-fly recalibration)
* linked quality score quantization to the BQSR stage, outputting a quantization histogram
* included the arguments used in BQSR to the GATK Report
* included all three tables (RG, QUAL and COVARIATES) to the GATK Report with empirical qualities
On-the-fly recalibration with GATK Report
* loads all tables from the GATKReport using existing infrastructure (with minor updates)
* implemented initialiazation of the covariates using BQSR's argument list
* reduced memory usage significantly by loading only the empirical quality and estimated quality reported for each bit set key
* applied quality quantization to the base recalibration
* excluded low quality bases from on-the-fly recalibration for mismatches, insertions or deletions
-- This behavior, which isn't obviously valuable at all, continued to grab and rethrow exceptions in the HMS that, if run without NT, would show up as more meaningful errors. Now HMS simply checks whether the throwable it received on error was a RuntimeException. If so, it is stored and rethrow without wrapping later. If it isn't, only in this case is the exception wrapped in a ReviewedStingException.
-- Added a QC walker ErrorThrowingWalker that will throw a UserException, ReviewedStingException, and NullPointerException from map as specified on the command line
-- Added IT that ensures that all three types are thrown properly (i.e., you catch a NullPointerException when you ask for one to be thrown) with and without threading enabled.
-- I believe this will finally put to rest all of these annoying HMS captures.
-- Use a LinkedHashMap not a TreeMap so iteration is faster.
-- Note that with a lot of stratifications the update0 is taking up a lot of time. For example, with 822 samples and functional class and sample on there are 100K contexts and 30% of the runtime is just in the update0 call
-- Now you always get SNP and indel metrics with VariantEval!
-- Includes Number of SNPs, Number of singleton SNPs, Number of Indels, Number of singleton Indels, Percent of indel sites that are multi-allelic, SNP to indel ratio, Singleton SNP to indel ratio, Indel novelty rate, 1 to 2 bp indel ratio, 1 to 3 bp indel ratio, 2 to 3 bp indel ratio, 1 and 2 to 3 bp indel ratio, Frameshift percent, Insertion to deletion ratio, Insertion to deletion ratio for 1 bp events, Number of indels in protein-coding regions labeled as frameshift, Number of indels in protein-coding regions not labeled as frameshift, Het to hom ratio for SNPs, Het to hom ratio for indels, a Histogram of indel lengths, Number of large (>10 bp) deletions, Number of large (>10 bp) insertions, Ratio of large (>10 bp) insertions to deletions
-- Updated VE integration tests as appropriate
-- Moved a variety of useful formatting routines for ratios, percentages, etc, into VariantEvalator.java so everyone can share. Code updated to use these routines where appropriate
-- Added variantWasSingleton() to VariantEvaluator, which can be used to determine if a site, even after subsetting to specific samples, was a singleton in the original full VCF
-- TableType, which used to be an interface, is now an abstract class, allowing us to implement some generally functionality and avoid duplication.
-- This included creating a getRowName() function that used to be hardcoded as "row" but how can be overridden.
-- #### This allows us implement molten tables, which are vastly easier to use than multi-row data sets. See IndelHistogram class (in later commit) for example of molten VE output
-- No more IndelLengthHistogram (superceded by IndelSummary in subsequent commit)
-- No more SamplePreviousGenotypes or PhaseStats
-- No more MultiallelicAFs
* fixed BadCigarFilter to filter out reads starting/ending in deletion and that have adjacent I/D events.
* added Unit tests for BadCigarFilter
* updated all exceptions in LocusIteratorByState to tell the user that he can instead run with -rf BadCigar
* added the BadCigar filter to ReduceReads and RealignTargetCreator (if your walker blows up with these malformed reads, you may want to add it too)
- Updated the documentation on the code
- Made the table.write() method private and updated necessary files.
- Added a constructor to GATKReport that takes GATKReportTables

This is important for quick turnaround in the analysis cycle of the new covariates. Also added a dummy unit test that doesn't really test anything (disabled), but helps in debugging.
Pulled out the functionality from Indel Realigner and Table Recalibrator into Utils.setupWriter to make everyone else's life's easier if they want to include the PG tag in their walkers.
Infrastructure:
* Added static interface to all different clipping algorithms of low quality tail clipping
* Added reverse direction pileup element event lookup (indels) to the PileupElement and LocusIteratorByState
* Complete refactor of the KeyManager. Much cleaner implementation that handles keys with no optional covariates (necessary for on-the-fly recalibration)
* EventType is now an independent enum with added capabilities. All functionality is now centralized.
BQSR and RecalibrateBases:
* On-the-fly recalibration is now generic and uses the same bit set structure as BQSR for a reduced memory footprint
* Refactored the object creation to take advantage of the compact key structure
* Replaced nested hash maps with single hash maps indexed by bitsets
* Eliminated low quality tails from the context covariate (using ReadClipper's write N's algorithm).
* Excluded contexts with N's from the output file.
* Fixed cycle covariate for discrete platforms (need to check flow cycle platforms now!)
* Redfined error for indels to look at the previous base in negative strand reads (using new PE functionality)
* Added the covariate ID (for optional covariates) to the output for disambiguation purposes
* Refactored CovariateKeySet -- eventType functionality is now handled by the EventType enum.
* Reduced memory usage of the BQSR script to 4
Tests:
* Refactored BQSRKeyManagerUnitTest to handle the new implementation of the key manager
* Added tests for keys without optional covariates
* Added tests for on-the-fly recalibration (but more tests are necessary)
Infrastructure:
* Generic BitSet implementation with any precision (up to long)
* Two's complement implementation of the bit set handles negative numbers (cycle covariate)
* Memoized implementation of the BitSet utils for better performance.
* All exponents are now calculated with bit shifts, fixing numerical precision issues with the double Math.pow.
* Replace log/sqrt with bitwise logic to get rid of numerical issues
BQSR:
* All covariates output BitSets and have the functionality to decode them back into Object values.
* Covariates are responsible for determining the size of the key they will use (number of bits).
* Generalized KeyManager implementation combines any arbitrary number of covariates into one bitset key with event type
* No more NestedHashMaps. Single key system now fits in one hash to reduce hash table objects overhead
Tests:
* Unit tests added to every method of BitSetUtils
* Unit tests added to the generalized key system infrastructure of BQSRv2 (KeyManager)
* Unit tests added to the cycle and context covariates (will add unit tests to all covariates)
-- TODO for ryan -- there are bugs in ActivityProfile code that I cannot fix right now :-(
-- UnitTesting framework for ActivityProfile -- needs to be expanded
-- Minor helper functions for ActiveRegion to help with unit tests
-- Refactored ART into clearer, simpler procedures. Attempted to merge shared code into utility classes.
-- Added some docs
-- Created a new, testable ActivityProfile that represents as a class the probability of a base being active or inactive
-- Separated band-pass filtering from creation of active regions. Now you can band pass filter a profile to make another profile, and then that is explicitly converted to active regions
-- Misc. utility functions in ActiveRegionWalker such as hasPresetActiveRegions()
-- Many TODOs in ActivityProfile.
GATKReport format changes:
- All non-data header lines are preceeded with a single pound ( #:)
- Every report now has a report header containing the version number and number of tables
- Every table has two lines of table header: The first explains the size of the table and the data types of each column, the second contains the table name and description.
- This new format will allow reports in the future to be gatherable.
- Changed the header format to include an end-of-line string ":;"
Added features:
- Simplified GATK Reports:
The constructor for a simplified GATK Report. Simplified GATK report are designed for reports that do not need the advanced functionality of a full GATK Report.
A simple GATK Report consists of:
- A single table
- No primary key ( it is hidden )
Optional:
- Only untyped columns. As long as the data is an Object, it will be accepted.
- Default column values being empty strings.
Limitations:
- A simple GATK report cannot contain multiple tables.
- It cannot contain typed columns, which prevents arithmetic gathering.
- Added a constructor to generate simplified GATK reports.
- Added a method to easily add data to simple GATK reports.
- Upgraded the input parser take advantage of the new file format (v1).
- Added the GATKReportGatherer, more usability cmoing in next versionof GATK Report. Curently, it can only add rows from one table to another. Added private methods in GATKReport to combine Tables and Reports, It is very conservative and will only gather if the table columns, as well as everything else matches. At the column level, it uses the (redundant) row ids to add new rows. It will throw an exception if it is overwriting data.
- Made some GATKReport methods public, and added more setters and getters.
- Added method that compares formats of two GATKReports, and added an equals method to verify all data inside.
- The gsalib for R now supports reading GATKReport v1 files in addition to legacy formats (v0.*)
- Added a GATKReportDataType enum to give column a certain data type. This must be specified when making a gatherable report. This enum contains several methods including a reverse lookup map.
- Added a data type field in GATKColumn, when a type is not specified, the unknown type is used. Unknown types should not be gathered.
Test changes:
- Updated Unit Tests for GATK Report v1. Added a test for the gatherer. Left one test disabled while we transition from v0 to v1.
- Updated the MD5 hashes in integration tests throughout the GATK.
Other changes:
- Added the gatherer functions to CoverageByRG
- Also added the scatterCount parameter in the Interval Coverage script
- Dropped support for reading in legacy GATKReport formats ( v0.*)
- Updated VariantEvalWalker to work with GATK Report v1, added a format String to all applicable DataPoints.
- Rewrote the read file method for GATK report files.
- Optimized the equals methods within GATKReport. The protected functions should only be called by the GATKReport methods.

This is a quick-and-dirty patch for the null pointer error Mauricio reported earlier.
Later on we might want to address in a more general way the fact that we validate user intervals
against the reference but not against the merged BAM header produced by the engine at runtime.
This fix is similar, but distinct from the earlier fix to GATKBAMIndex. If we fail to read in
a complete 3-integer bin header from the BAM schedule file that the engine has written, throw a
ReviewedStingException (since this is our problem, not the user's) rather than allowing a
cryptic buffer underflow error to occur.
Note that this change does not fix the underlying problem in the engine, if there is one
(there may be an as-yet-undetected bug in the code that writes the bam schedule). It will
just make it easier for us to identify what's going wrong in the future.
GATKBAMIndex would allow an extremely confusing BufferUnderflowException to be
thrown when a BAM index file was truncated or corrupt. Now, a UserException is
thrown in this situation instructing the user to re-index the BAM.
Added a unit test for this case as well.
-- A cleaner table output (molten). For those interested in seeing how this can be done with GATKReports look here for a nice clean example
-- Integration tests
-- Minor improvements to GATKReportTable with methods to getPrimaryKeys
-- We weren't properly handling the case where a site had both a SNP and indel in both eval and comp. These would naturally pair off as SNP x SNP and INDEL x INDEL in eval, but we'd still invoke update2 with (null, SNP) and (null, INDEL) resulting most conspicously as incorrect false negatives in the validation report.
-- Updating misc. integrationtests, as the counting of comps (in particular for dbSNP) was inflated because of this effect.
-Running the GATK with the -et NO_ET or -et STDOUT options now
requires a key issued by us. Our reasons for doing this, and the
procedure for our users to request keys, are documented here:
http://www.broadinstitute.org/gsa/wiki/index.php/Phone_home
-A GATK user key is an email address plus a cryptographic signature
signed using our private key, all wrapped in a GZIP container.
User keys are validated using the public key we now distribute with
the GATK. Our private key is kept in a secure location.
-Keys are cryptographically secure in that valid keys definitely
came from us and keys cannot be fabricated, however keys are not
"copy-protected" in any way.
-Includes private, standalone utilities to create a new GATK user key
(GenerateGATKUserKey) and to create a new master public/private key
pair (GenerateKeyPair). Usage of these tools will be documented on
the internal wiki shortly.
-Comprehensive unit/integration tests, including tests to ensure the
continued integrity of the GATK master public/private key pair.
-Generation of new user keys and the new unit/integration tests both
require access to the GATK private key, which can only be read by
members of the group "gsagit".
-- Includes paired end status (T/F)
-- Includes count of reads used in calculation
-- Includes simple read type (2x76 for example)
-- Better handling of insert size, read length when there's no data, or the data isn't paired end by emitting NA not 0
-- ReadGroupProperties: Emits a GATKReport containing read group, sample, library, platform, center, median insert size and median read length for each read group in every BAM file.
-- Median tool that collects up to a given maximum number of elements and returns the median of the elements.
-- Unit and integration tests for everything.
-- Making name of TestProvider protected so subclasses and override name more easily
* All contexts with 'N' bases are now collapsed as uninformative
* Context size is now represented internally as a BitSet but output as a dna string
* Temporarily disabled sorted outputs because of null objects
* Turns DNA sequences (for context covariates) into bit sets for maximum compression
* Allows variable context size representation guaranteeing uniqueness.
* Works with long precision, so it is limited to a context size of 31 bases (can be extended with BigNumber precision if necessary).
* Unit Tests added
-- As these represent the bulk of the StingExceptions coming from BAMSchedule and are caused by simple problems like the user providing bad input tmp directories, etc.
-- DoC now by default ignores bases with reference Ns, so these are not included in the coverage calculations at any stage.
-- Added option --includeRefNSites that will include them in the calculation
-- Added integration tests that ensures the per base tables (and so all subsequent calculations) work with and without reference N bases included
-- Reorganized command line options, tagging advanced options with @Advanced
* The tailSet generated every time we flush the reads stash is still being affected by subsequent clears because it is just a pointer to the parent element in the original TreeSet. This is dangerous, and there is a weird condition where the clear will affects it.
* Fix by creating a new set, given the tailSet instead of trying to do magic with just the pointer.
When aggregating raw BAM file spans into shards, the IntervalSharder tries to combine
file spans when it can. Unfortunately, the method that combines two BAM file
spans was seriously flawed, and would produce a truncated union if the file spans
overlapped in certain ways. This could cause entire regions of the BAM file containing
reads within the requested intervals to be dropped.
Modified GATKBAMFileSpan.union() to correct this problem, and added unit tests
to verify that the correct union is produced regardless of how the file spans
happen to overlap.
Thanks to Khalid, who did at least as much work on this bug as I did.
so Ryan can work on the recalibration on the fly without breaking the build. Supposedly all the secret sauce is in the BQSR walker, which sits in private.
* added support to base before deletion in the pileup
* refactored covariates to operate on mismatches, insertions and deletions at the same time
* all code is in private so original BQSR is still working as usual in public
* outputs a molten CSV with mismatches, insertions and deletions, time to play!
* barely tested, passes my very simple tests... haven't tested edge cases.
premature push from my part. Roger is still working on the new format and we need to update the other tools to operate correctly with the new GATKReport.
This reverts commit aea0de314220810c2666055dc75f04f9010436ad.
- Added the GATKReportGatherer
- Added private methods in GATKReport to combine Tables and Reports
- It is very conservative and it will only gather if the table columns, match.
- At the column level it uses the (redundant) row ids to add new rows. It will throw an exception if it is overwriting data.
Added the gatherer functions to CoverageByRG
Also added the scatterCount parameter in the Interval Coverage script
Made some more GATKReport methods public
The UnitTest included shows that the merging methods work
Added a getter for the PrimaryKeyName

* Adding the context covariate standard in both modes (including old CountCovariates) with parameters
* Updating all covariates and modules to use GATKSAMRecord throughout the code.
* BQSR now processes indels in the pileup (but doesn't do anything with them yet)
* calculates and interprets the coverage of a given interval track
* allows to expand intervals by specified number of bases
* classifies targets as CALLABLE, LOW_COVERAGE, EXCESSIVE_COVERAGE and POOR_QUALITY.
* outputs text file for now (testing purposes only), soon to be VCF.
* filters are overly aggressive for now.
-- This is a partial fix for the problem with uploading S3 logs reported by Mauricio. There the problem is that the java.io.tmpdir is not accessible (network just hangs). Because of that the s3 upload fails because the underlying system uses tmpdir for caching, etc. As far as I can tell there's no way around this bug -- you cannot overload the java.io.tmpdir programmatically and even if I could what value would we use? The only solution seems to me is to detect that tmpdir is hanging (how?!) and fail with a meaningful error.
per Mark's recommendation to reuse the Indel Realigner tag that made it to the SAM spec. The Alignment end tag is still "OE" as there is no official tag to reuse.
* Added annotations for reads that had been soft clipped prior to being reduced so that we can later recuperate their original alignments (start and end).
* Tags keep the alignment shifts, not real alignment, for better compression
* Tags are defined in the GATKSAMRecord
* GATKSAMRecord has new functionality to retrieve original alignment start of all reads (trimmed or not) -- getOriginalAlignmentStart() and getOriginalAligmentEnd()
* Updated ReduceReads MD5s accordingly
AllelePair is being mean and not telling me what genotype it sees when it finds a non-diploid genotype, but i suspect it's a no-call (".") rather than a no call ("./.").
Eric reported this bug due to the reduced reads failing with an index out of bounds on what we thought was a deletion, but turned out to be a read starting with insertion.
* Refactored PileupElement to distinguish clearly between deletions and read starting with insertion
* Modified ExtendedEventPileup to correctly distinguish elements with deletion when creating new pileups
* Refactored most of the lazyLoadNextAlignment() function of the LocusIteratorByState for clarity and to create clear separation between what is a pileup with a deletion and what's not one. Got rid of many useless if statements.
* Changed the way LocusIteratorByState creates extended event pileups to differentiate between insertions in the beginning of the read and deletions.
* Every deletion now has an offset (start of the event)
* Fixed bug when LocusITeratorByState found a read starting with insertion that happened to be a reduced read.
* Separated the definitions of deletion/insertion (in the beginning of the read) in all UG annotations (and the annotator engine).
* Pileup depth of coverage for a deleted base will now return the average coverage around the deletion.
* Indel ReadPositionRankSum test now uses the deletion true offset from the read, changed all appropriate md5's
* The extra pileup elements now properly read by the Indel mode of the UG made any subsequent call have a different random number and therefore all RankSum tests have slightly different values (in the 10^-3 range). Updated all appropriate md5s after extremely careful inspection -- Thanks Ryan!
phew!
reporting malformed BAMs was actually misreporting any error that happened in the Picard layer
as a BAM ERROR.
Specifically changing PicardException to report as a ReviewedStingException; we might want to
change it in the future. I'll followup with the Picard team to make sure they really, really
want PicardException to inherit from SAMException.
-- Disturbingly, fixing this bug doesn't actually cause an test failures.
-- Wrote a new QCRefWalker to actually check in detail that the reference bases coming into the RefWalker are all correct when comparing against a clean uncached load of the contig bases directly.
-- However, I cannot run this tool due to some kind of weird BAM error -- sending this on to Matt
-- Missing BAMs were appearing as StingExceptions
-- Missing VCFs were showing up as CommandLineErrors, but it's clearer for them to be CouldNotReadInputFile exceptions
-- Added integration tests to ensure missing BAMs, VCFs, and -L files are properly thrown as CouldNotReadInputFile exceptions
-- Added path to standard b37 BAM to BaseTest
-- Cleaned up code in SAMDataSource, removing my parallel loading code as this just didn't prove to be useful.
-- Instead issue a warning when a large (>1MB) record is encountered
-- Optimized ref.getBytes()[i] => (byte)ref.charAt(i), which avoids an implicit O(n) allocation each iteration through computeReverseClipping()
-- samtools can emit alleles where the ref is 42M Ns and this caused the GATK (via tribble) to hang in several places.
-- Tribble was updated so we actually could read the line properly (rev. to 51 here).
-- Still the parsing algorithms in the GATK aren't happy with such a long allele. Instead of optimizing the code around an improper use case I put in a limit of 2^16 bp for any allele, and throw a meaningful exception when encountered.
CalibrateGenotypeLikelihoods supports using an external VCF as input for genotype likelihoods. Currently can be a per-sample VCF, but has un-implemented methods for allowing a read-group VCF to be used.
Removed the old constrained genotyping code from UGE -- the trellis calculated is exactly the same as that done in the MLE AC estimate; so we should just re-use that one.
* using the filter() instead of map() makes for a cleaner walker.
* renaming the unit tests to make more sense with the other unit and integration tests
* if the adaptor boundary is more than MAXIMUM_ADAPTOR_SIZE bases away from the read, then let's not clip anything and consider the fragment to be undetermined for this read pair.
* updated md5's accordingly
QScript accessor to QSettings to specify a default runName and other default function settings.
Because log files are no longer pseudo-random their presense can be used to tell if a job without other file outputs is "done". For now still using the log's .done file in addition to original outputs.
Gathered log files concatenate all log files together into the stdout.
InProcessFunctions now have PrintStreams for stdout and stderr.
Updated ivy to use commons-io 2.1 for copying logs to the stdout PrintStream. Removed snakeyaml.
During graph tracking of outputs the Index files, and now BAM MD5s, are tracked with the gathering of the original file.
In Queue generated wrappers for the GATK the Index and MD5s used for tracking are switched to private scope.
Added more detailed output when running with -l DEBUG.
Simplified graphviz visualization for additional debugging.
Switched usage of the scala class 'List' to the trait 'Seq' (think java.util.ArrayList vs. using the interface java.util.List)
Minor cleanup to build including sending ant gsalib to R's default libloc.
To support this, refactored code that computes consensus alleles. To ease merging of mulitple alt alleles, we create a single vc for each alt alleles and then use VariantContextUtils.simpleMerge to carry out merging, which takes care of handling all corner conditions already. In order to use this, interface to GenotypeLikelihoodsCalculationModel changed to pass in a GenomeLocParser object (why are these objects to hard to handle??).
More testing is required and feature turned off my default.
-- Call sets with indels > 50 bp in length are tagged as CNVs in the tag (following the 1000 Genomes convention) and were unconditionally checking whether the CNV is already known, by looking at the known cnvs file, which is optional. Fixed. Has the annoying side effect that indels > 50bp in size are not counted as indels, and so are substrated from both the novel and known counts for indels. C'est la vie
-- Added integration test to check for this case, using Mauricio's most recent VCF file for NA12878 which has many large indels. Using this more recent and representative file probably a good idea for more future tests in VE and other tools. File is NA12878.HiSeq.WGS.b37_decoy.indel.recalibrated.vcf in Validation_Data
This error was due to the ReadClipper change of contract. Before the read utils would return null if a read was entirely clipped, now it returns an empty (safe) GATKSAMRecord.
* Downsampling is now a parameter to the walker with default value of 0 (no downsampling)
* Downsampling selects reads at random at the variant region window and strives to achieve uniform coverage if possible around the desired downsampling value.
* Added integration test
* Knuth-shuffle is a simple, yet effective array permutator (hope this is good english).
* added a simple randomSubset that returns a random subset without repeats of any given array with the same probability for every permutation.
* added unit tests to both functions
* Modified cleanCigarShift to allow insertions in the beginning and end of the read
* Allowed cigars starting/ending in insertions in the systematic ReadClipper tests
* Updated all ReadClipper unit tests
* ReduceReads does not hard clip leading insertions by default anymore
* SlidingWindow adjusts start location if read starts with insertion
* SlidingWindow creates an empty element with insertions to the right
* Fixed all potential divide by zero with totalCount() (from BaseCounts)
* Updated all Integration tests
* Added new integration test for multiple interval reducing
-- Automatic detection of most recent version of GATK release (just tell the script now to use 1.2, 1.3, and 1.4)
-- Uses 1.4 now
-- By default we do 9 runs of each non-parallel test
-- In PathUtils added convenience utility to find most recent release GATK jar with a specific release number
Turns out that because the RTC is the first walker to 'correctly' tree reduce according to functional programming
standards, the RTC has revealed a few problems with the tree reducer holding on to too much data. This is the first
and smaller of two commits to reduce memory consumption. The second commit will likely be pushed after GATK1.4 is
released.
* Creates an empty GATKSAMRecord with empty (not null) Cigar, bases and quals. Allows empty reads to be probed without breaking.
* All ReadClipper utilities now emit empty reads for fully clipped reads
* Described the ReadClipper contract in the top of the class
* Added contracts where applicable
* Added descriptive information to all tools in the read clipper
* Organized public members and static methods together with the same javadoc
These functions are methods of the read, and supplement getAlignmentStart() and getUnclippedStart() by calculating the unclipped start counting only soft clips.
* Removed from ReadUtils
* Added to GATKSAMRecord
* Changed name to getSoftStart() and getSoftEnd
* Updated third party code accordingly.
* Removed all clipping functionality from ReadUtils (it should all be done using the ReadClipper now)
* Cleaned up functionality that wasn't being used or had been superseded by other code (in an effort to reduce multiple unsupported implementations)
* Made all meaningful functions public and added better comments/explanation to the headers
For simplified access to the hard clipping utilities. No need to create a ReadClipper object if you are not doing multiple complicated clipping operations, just use the static methods.
examples:
ReadClipper.hardClipLowQualEnds(2);
ReadClipper.hardClipAdaptorSequence();
The algorithm wasn't accounting for the case where the read is the reverse strand and the insert size is negative.
* Fixed and rewrote for more clarity (with Ryan, Mark and Eric).
* Restructured the code to handle GATKSAMRecords only
* Cleaned up the other structures and functions around it to minimize clutter and potential for error.
* Added unit tests for all 4 cases of adaptor boundaries.
-- Support for collecting resources info from DRMAA runners
-- Disabled the non-standard mem_free argument so that we can actually use our own SGE cluster gsa4
-- NCoresRequest is a testing queue script for this.
-- Added two command line arguments:
-- multiCoreJerk: don't request multiple cores for jobs with nt > 1. This was the old behavior but it's really not the best way to run parallel jobs. Now with queue if you run nt = 4 the system requests 4 cores on your host. If this flag is thrown, though, it will only request 1 and you'll just use 4, like a jerk
-- job_parallel_env: parallel environment named used with SGE to request multicore jobs. Equivalent to -pe job_parallel_env NT for NT > 1 jobs
* New ClippingOp REVERT_SOFTCLIPPED_BASES turns soft clipped bases into matches.
* Added functionality to clipping op to revert all soft clip bases in a read into matches
* Added revertSoftClipBases function to the ReadClipper for public use
* Wrote systematic unit tests
Minor changes to ValidationSiteSelector logic (SampleSelectors determine whether a site is valid for output, no actual subset context need be operated on beyond that determination). Implementation of GL-based site selection. Minor changes to EJG.
UGBoundAF has to go in at some point. In the process of rewriting the math for bounding the allele frequency (it was assuming uniform tails, which is silly since i derived the posterior distribution in closed form sometime back, just need to find it)
Creating a single temporary directory per ant test run instead of a putting temp files across all runs in the same directory.
Updated various tests for above items and other small fixes.
fixed issue where a read starting with an insertion followed by a deletion would break, clipper can now safely clip the insertion and the deletion if that's the case.
note: test is turned off until contract changes to allow hanging insertions (left/right).
* fixed edge case when requested to hard clip beginning of a read that had hanging soft clipped bases on the left tail.
* fixed edge case when requested to hard clip end of a read that had hanging soft clipped bases on the right tail.
* fixed AlignmentStart of a clipped read that results in only hard clips and soft clips
note: added tests to all these beautiful cases...
This change and my previous change have dropped runtime when dynamically merging 2k BAM files from 72.6min/1M reads to 46.8sec/1M reads.
Note that many of these changes are stopgaps -- the real problem is the way ReadWalkers interface with Picard, and I'll have to work with
Tim&Co to produce a more maintainable patch.
-- Serial version can be re-enabled with a static boolean, if we decide to return to the serial version
-- Comparison of serial and parallel reader with cached and uncached files:
Initialization time: serial with 500 fully cached BAMs: 8.20 seconds
Initialization time: serial with 500 uncached BAMs : 197.02 seconds
Initialization time: parallel with 500 fully cached BAMs: 30.12 seconds
Initialization time: parallel with 500 uncached BAMs : 75.47 seconds
* expanded the systematic cigar string space test framework Roger wrote to all tests
* moved utility functions into Utils and ReadUtils
* cleaned up unused classes
caught a bug in the hard clipper where it does not account for hard clipping softclipped bases in the resulting cigar string, if there is already a hard clipped base immediately after it.
* updated unit test for hardClipSoftClippedBases with corresponding test-case.
shifted the contract to functions that operate on reference based coordinates. The clipper should do the right thing with unmapped reads, but it needs more testing (Ryan is using it at the moment and says it works). Will write some unit tests.
* added functions to create synthetic reads for unit testing with reasonable default parameters
* added more functions to create synthetic reads based on cigar string + bases and quals.
bug: When performing multiple hard clip operations in a read that has indels, if the N+1 hardclip requests to clip inside an indel that has been removed by one of the (1..N) previous hardclips, the hard clipper would go out of bounds.
fix: dynamically adjust the boundaries according to the new hardclipped read length. (this maintains the current contract that hardclipping will never return a read starting or ending in indels).
-- Uses 8 threads to load BAM files and indices in parallel, decreasing costs to read thousands of BAM files by a significant amount
-- Added logger.info message noting progress and cost of reading low-level BAM data.
-- Now properly handles the case where a sample isn't present (no longer adds a null to the genotypes list)
-- Fix for logic failure where if the number of requested samples equals the number of known genotypes then all of the records were returned, which isn't correct when there are missing samples.
-- Unit tests added to handle these cases
Turns out that someone previously upped the declared size of a ROD shard to 100M bases, making
each ROD shard larger than the size of chr20. Why didn't we see this in Stable? Because the
ShardStrategy/ShardStrategyFactory mechanism was dutifully ignoring the shard size specification.
When I rolled the ShardStrategy/ShardStrategyFactory mechanics back into the DataSources as part
of the async I/O project, I inadvertently reenabled this specifier.
PreQC parses file with spaces in sample names by using tabs only.
PostQC allows passing the file names for the evals so that flanks can be evaled.
BaseTest's network temp dir now adds the user name to the path so files aren't created in the root.
HybridSelectionPipeline:
- Updated to latest versions of reference data.
- Refactored Picard parsing code replacing YAML.
This has implications for both Qscript authors and CommandLineFunction authors.
Qscript authors:
You no longer need to (and in fact must not) manually escape String values to
avoid interpretation by the shell when setting up Walker parameters. Queue will
safely escape all of your Strings for you so that they'll be interpreted literally. Eg.,
Old way:
filterSNPs.filterExpression = List("\"QD<2.0\"", "\"MQ<40.0\"", "\"HaplotypeScore>13.0\"")
New way:
filterSNPs.filterExpression = List("QD<2.0", "MQ<40.0", "HaplotypeScore>13.0")
CommandLineFunction authors:
If you're writing a one-off CommandLineFunction in a Qscript and don't really
care about quoting issues, just keep doing things the direct, simple way:
def commandLine = "cat %s | grep -v \"#\" > %s".format(files, out)
If you're writing a CommandLineFunction that will become part of Queue and
will be used by other QScripts, however, it's advisable to do things the
newer, safer way, ie.:
When you construct your commandLine, you should do so ONLY using the API methods
required(), optional(), conditional(), and repeat(). These will manage quoting
and whitespace separation for you, so you shouldn't insert quotes/extraneous
whitespace in your Strings. By default you get both (quoting and whitespace
separation), but you can disable either of these via parameters. Eg.,
override def commandLine = super.commandLine +
required("eff") +
conditional(verbose, "-v") +
optional("-c", config) +
required("-i", "vcf") +
required("-o", "vcf") +
required(genomeVersion) +
required(inVcf) +
required(">", escape=false) + // This will be shell-interpreted
required(outVcf)
I've ported the Picard/Samtools/SnpEff CommandLineFunction classes to the new
system, so you'll get free shell escaping when you use those in Qscripts just
like with walkers.
-- VariantSummary now includes novelty of CNVs by reciprocal overlap detection using the standard variant eval -knownCNVs argument
-- Genericizes loading for intervals into interval tree by chromosome
-- GenomeLoc methods for reciprocal overlap detection, with unit tests
Also includes convenience parameters for specifying the IO/CPU threading balance outside of a tag. Will be killed when
Queue gets better support for tagged arguments (hopefully soon).
-- Performance optimizations
-- Tables now are cleanly formatted (floats are %.2f printed)
-- VariantSummary is a standard report now
-- Removed CompEvalGenotypes (it didn't do anything)
-- Deleted unused classes in GenotypeConcordance
-- Updates integration tests as appropriate
-- Updating MD5s for UG to reflect that what was previously called ./.:.:10:0,0,0 is now just ./. Eric will fix long-standing bug in QD observed from this change
-- VFW MD5s restored to their old correct values. There was a bug in my implementation to caused the genotypes to not be parsed from the lazy output even through the header was incorrect.
This syntax predates the ability to have multiple -L arguments, is
inconsistent with the syntax of all other GATK arguments, requires
quoting to avoid interpretation by the shell, and was causing
problems in Queue.
A UserException is now thrown if someone tries to use this syntax.
-- Now you provide a LazyParsing object
-- LazyGenotypesContext now knows nothing about the VCF parser itself. The parser holds all of the necessary data to parse the VCF genotypes when necessarily, and the LGC only has a pointer to this object
-- Using new interface added LazyGenotypesContext to unit tests with a simple lazy version
-- Deleted VCFParser interface, as it was no longer necessary
-- With our GenotypesContext class we can naturally create a LazyGenotypesContext subclass that does the on-demand loading.
-- This new class was replaced all of the old, complex functionality
-- Better still, there were many cases were the genotypes were being loaded unnecessarily, resulting in efficiency. This was detected because some of the integration tests changed as the genotypes were no longer being parsing unnecessarily
-- Misc. bug fixes throughout the system
-- Bug fixes for PhaseByTransmission with new GenotypesContext
-- We should no longer have md5s changing because of hashmaps changing their sort order on us
-- Added GenotypeLikelihoodsUnitTests
-- Refactored ExactAFCaclculation to put the PL -> QUAL calculation in the GenotypeLikelihoods class to avoid the code copy.
-- New approach to making VariantContexts modeled on StringBuilder
-- No more modify routines -- use VariantContextBuilder
-- Renamed isPolymorphic to isPolymorphicInSamples. Same for mono
-- getChromosomeCount -> getCalledChrCount
-- Walkers changed to use new VariantContext. Some deprecated new VariantContext calls remain
-- VCFCodec now uses optimized cached information to create GenotypesContext.
-- Major change to how chromosomeCounts is computed. Now NO_CALL alleles are always excluded. So ChromosomeCounts(A/.) is 1, the previous result would have been 2.
-- Naming changes for getSamplesNameInOrder()
-- Now these routines all iterate in sample name order (genotypes.iterateInSampleNameOrder) so that the results of UG and the annotator do not depend on the particular order of samples we see for the exact model and the RankSumTest
-Modified the SnpEff parser to work with the SnpEff 2.0.4 VCF output format
-Assigning functional classes and effect impacts now handled directly
by SnpEff rather than the GATK
-Removed support for SnpEff 2.0.2, as we no longer trust the output of that
version since it doesn't exclude effects associated with certain nonsensical
transcripts. These effects are excluded as of 2.0.4.
-Updated unit and integration tests
This support is based on a *release-candidate* of SnpEff 2.0.4, and so is subject
to change between now and the next GATK release.
compressed the representation of the reduce reads counts by offset results in 17% average compression in final BAM file size.
Example compression -->
from : 10, 10, 11, 11, 12, 12, 12, 11, 10
to: 10, 0, 1, 1,2, 2, 2, 1, 0
-- I have no idea why I named this InferredGeneticContext, a totally meaningless term
-- Renamed to CommonInfo.
-- Made package protected, as no one should use this outside of VariantContext and Genotype
-- UGEngine was using IGC constant, but it's now using the public one in VariantContext.
-- Enables further sophisticated optimizations, as this class can be smarter about storing the data and will directly support operations like subset to samples
-- All instances in the gatk that used Map<String, Genotype> now use GenotypeMap type.
-- Amazingly, there were many places where HashMap<String, Genotype> is used, so that the order of the genotypes is technically undefined and could be dangerous. Now everything uses GenotypeMap with a specific ordering of samples (by name)
-- Integrationtests updated and all pass
-- This is a more convenient accesssor than subContextOfGenotypes, represents nearly all of the use cases of the former function, and potentially can be implemented more efficiently.
The primary use of this stratification is to provide a mechanism to divide asssessment of a call set up by whether a variant overlaps an interval or not. I use this to differentiate between variants occurring in CCDS exons vs. those in non-coding regions, in the 1000G call set, using a command line that looks like:
-T VariantEval -R human_g1k_v37.fasta -eval 1000G.vcf -stratIntervals:BED ccds.bed -ST IntervalStratification
Note that the overlap algorithm properly handles symbolic alleles with an INFO field END value. In order to safely use this module you should provide entire contigs worth of variants, and let the interval strat decide overlap, as opposed to using -L which will not properly work with symbolic variants.
Minor improvements to create() interval in GenomeLocParser.
* Generalized the concept of a synthetic read to cread both running consensus and a synthetic reads of filtered data.
* Synthetic reads can now have deletions (but not insertions)
* New reduced read tag for filtered data synthetic reads *(RF)*
* Sliding window header now keeps information of consensus and filtered data
* Synthetic reads are created simultaneously, new functionality is controlled internally by addToSyntheticReads
-- A bit of code cleanup in VCFUtils
-- VariantEval table to create 1000G Phase I variant summary table
-- First version of 1000G Phase I summary table Qscript
Table codec now yells at users for not providing a HEADER with the table - parsing tables without a header line was causing the first line of the file to be eaten.
Table feature now has a toString method.
These are minor bug fixes.
when constructing a GATKSAMRecord from scratch, we should set "mRestOfBinaryData" to null so the BAMRecord doesn't try to retrieve missing information from the non-existent bam file.
-- vcfWriter2 was never being closed in onTraversalDone(), so the on the fly index file was being created but never actually properly written to the file.
-- This bug is ultimately due to the inability of the GATK to allow multiple VCF output writers as @Output arguments, though
-- Removed the unnecessary local variable iFraction, = 1000 * the input fraction argument. Now the system just uses a double random number and compares to the input fraction at all. Is there some subtle reason I don't appreciate for this programming construct?
The GATK engine will now provide a GATKSAMRecord to all tools which incorporates the functionality used by the GATK to the bam file (ReadGroups, Reduced Reads, ...).
* No tools should create SAMRecord anymore, use GATKSAMRecord instead *
-- scatterLocusIntervals master utility
-- Moved around some general functionality from GenomeLocSortedSet to GenomeLoc
-- Util function for reversing a list (List<T> -> List<T>, unlike Collections version)
-- DoC is PartitionType.INTERVAL
-- Significant unit tests on new functionality (all passing)
-- Ready for real-world testing, as soon as I can get LocusScatterFunction.scala to actually work
-- Added PartitionType.READ, and associated ReadScatterFunction. ReadScatterFunction is literally just ContigScatterFunction until someone wants to implement something better
-- LocusWalkers (and subclasses RodWalkers and RefWalkers) are by default PartitionType.LOCUS.
Bases that were excluded for MQ and BQ filters are now contributing to the MQ RMS (but not to consensus base counts and variant/not variant region triggers).
Reducing the reference bases to '=' results in an extra compression of 13% on average. The GATK is not ready to handle files with '=' bases, and the decision was to implement this a an engine support, not a part of ReduceReads.
These walkers should not be scatter gatherable. Annotating them accordingly so that Queue doesn't allow a less than knowledgeable user to try and scatter/gather VQSR.
-- Supports ReadBackedPileup -> FragmentCollection as before
-- Added support for List<SAMRecord> -> FragmentCollection for Ryan's haplotype caller
-- General cleanup, renaming, move to separate package, more extensive unit tests, etc.
-- Added toFragment() function to ReadBackedPileup interface
First, I'm sure there's a better way to do this, but I wanted to create a single commit summarizing the changes from my branch SamRecordFactory. What's the best way to do this? Rebase?
Now, on to the changes here:
-- Picard added a SamRecordFactory that is used to create instances the subclass SamRecord or BAMRecord. This factory allows us to have low-level picard readers (SamFileReader) create objects of type GATKSamRecord. The abomination of the extends and contains GATKSamRecord is now gone. GATKSamRecords are now produced by this factory, the GATK provides this factory to our SamFileReaders, and everything works with GATKSamRecord just extending BAMRecord. This results in up to a 2x performance improvement in writing BAMs and a ~10% improvement when reading BAMs files.
-- As a consequence of this, we no longer officially support SAM records. Attempting to create SAMRecord objects with the factory will throw a user exception.
-- Created a standard NGSPlatform enum, and GATKSamRecords support efficiently obtaining this value. The real BQSR (not the copy indel version) got the efficient code to use this. Please add all future platforms to this enum.
-- GATKSamRecord no longer supports using the OQ or defaultBaseQuality. This is performed in a wrapper iterator that's only added when these command line options are used.
-- ReducedRead code has been moved from ReadUtils until efficiency caching assessors in GATKSamRecord.
-- ArtificialSamUtils creates GATKSamRecords now, just SAMRecords. Added code here to create artifical pairs and using that code to create artificial ReadBackedPileups with specific properties
-- New smarter algorithm for FragmentPileup. This new code is up to 3x faster than the previous version, and is lazy so is more efficient when no overlapping pairs are actually in the pileup. Created extensive DataProvider driven UnitTest. Added Caliper-based benchmarking system to characterize the performance differences between the old and new algorithms. TODO still remains to make a efficient version that works for non-pileups for the HaplotypeCaller
Moved gsalib and queueJobReport.R to embeddable namespaced locations.
Updated packager dependencies/dir to add an @includes which filters the embedded fileset.
RScriptExecutor can now JIT compiles the gsalib.
RScriptExecutor uses ProcessController and sends the Rscript output to java's stdout when run under -l DEBUG.
Refactored ProcessController and IOUtils from Queue to Sting Utils.
Added more unit tests to ProcessController along with a utility class to hard stop OutputStreams at a specified byte count.
Replaced uses of some IOUtils with Apache Commons IO.
ShellJobRunner refactored to use direct ProcessController and now kills jobs on shutdown.
Better QGraph responsiveness on shutdown by using Object.wait() instead of Thread.sleep().
-- removed intermiate functions. Now only original version and best optimized new version remain
-- Moved general artificial read backed pileup creation code into ArtificialSamUtils
- Sites with missing genotypes in pairs/trios are handled as follows:
-- Missing child -> Homozygous parents are phased, no transmission probability is emitted
-- Two individuals missing -> Phase if homozygous, no transmission probability is emitted
-- One parent missing -> Phased / transmission probability emitted
- Mutation prior set as argument
-- Uses mayOverlapRoutine in ReadUtils
-- Attempts to be smart when doing overlap calculation, to avoid unnecessary allocations
-- PileupElement now comparable (sorts on offset than on start)
-- Caliper microbenchmark to assess performance
Moved the validation of the GATKSamRecord to the MalformedReadFilter with the intent to make the read filter the ultimate validation location for sam records. This way we can opt to filter out malformed reads if we know what we are doing or blow up otherwise.
- Adapted to get the trio information from the SampleDB (i.e. from Pedigree file (ped)) => Multiple trios can be passed as argument
- Mendelian violations and trio phasing possibilities are pre-calculated and stored in Maps. => Runtime is ~3x faster
- Genotype combinations possible only given two MVs are now given a squared MV prior (e.g. 0/0+0/0=>1/1 is given 10^-16 prior if the MV prior is 10^-8)
- Corrected bug: In case the best genotype combination is Het/Het/Het, the genotypes are now set appropriately (before original genotypes were left even if they weren't Het/Het/Het)
- Basic reporting added:
-- mvf argument let the user specify a file to report remaining MVs
-- When the walker ends, some basic stats about the genotype reconfiguration and phasing are output
Known problems:
- GQ is not recalculated even if the genotype changes
Possible improvements:
- Phase partially typed trios
- Use standard Allele/Genotype Classes for the storage of the pre-calculated phase
This commit contains:
- IntronLossGenotyper is brought into its current incarnation
- A couple of simple new filters (ReadName is super useful for debugging, MateUnmapped is useful for selecting out reads that may have a relevant unaligned mate)
- RFA now matches my current local repository. It's in flux since I'm transitioning to the new traversal type.
+ the triggering read stash pilot required me to change the scope of some of the variables in the ReadClipping code, private -> protected. Those are all the changes there.
- MendelianViolation restored to its former glory (and an annotator module that uses the likelihood calculation has been added)
+ use this rather than a hard GQ threshold if you're doing MV analyses.
- Some miscellaneous QScripts
-- all of the methods in the class must be synchronized or the internal state can be inconsistent with the contract invariant when entering the class in a non-synchronized method, even when that method doesn't care about the object's internal state
-- SimpleTimer is now threadsafe using synchronized method keywords
-- Bug fix for alignmentToByteArray() where the N case was refPos++ not the now correct refPos += elementLength
Having SnpEff grouped with the Experimental annotations was proving problematic, since it
requires a rod. Placing it in its own group should improve the situation somewhat, making it
easier to request "all annotations except for SnpEff".
This allows the annotation classes to perform any necessary initialization/validation.
For example, it allows the SnpEff annotator to (among other things) validate its rod binding.
This will prevent a NullPointerException when SnpEff annotation is requested but no rod binding
is present.
Added an integration test to cover this case so that it doesn't break again.
-- Changes associated code throughout the codebase
-- Updated necessary (but minimal) UnitTests to reflect new behavior
-- Much better makealleles() function in VC.java that enforces a lot of key constraints in VC
-- For no apparent reason we were using a HashSet to store the ReadFilters, so the order of operations was really arbitrarily applied. The order now is
(1) the order of the walker intrinsic filters
(2) read group black list (if provided)
(3) command line filters (if provided)
-- The GATK will now throw a user exception if it opens a SAM/BAM file that doesn't have at least one RG defined
-- LIBS again throws an error if the complete list of samples isn't provided
-- Updating ExmpleCountLociPipeline test to use the well-formated versions of the exampleBAM and exampleFASTA files in testdata, instead of the old broken ones in validation_data.
-- Convenience constructors for UserExceptions.MalformedBAM
-- Right now we cannot process BAM files without read groups because we enforce the samples list to not be empty when there's a SAM record. Now if there are reads and there are no samples we add the "null" sample so that LIBS walks the reads properly
-- the underlying data structure is still present, but until I decide what to do for the extensible system I've completely disabled the subsystem
-- Added code to merge Samples, so that a mostly full record can be merged with a consistent empty record. If the two records are inconsistent, an error is thrown
-- addSample() in Sample.class now invokes mergeSample() when appropriate
-- Validation types are now only STRICT or SILENT
-- Validation code implemented in SampleDBBuilder
-- Extensive unit tests for SampleDBBuilder
-- Passes significiant unit tests
-- Implicit sample creation for mom / dad when you create single samples
-- Continuing cleanup of Sample and SampleDataSource
-- These could be simplied in their downstream uses
-- Or they could be replaced with a generic getSAMFileHeaders() function and then apply the getSamples(header) as desired downstream
-- A nearly identical piece of code already lived in SampleUtils. Now there are two functions, one taking a regular header and another grabbing the merged header from the GATK engine itself. Much cleaner
If both ends of the interval falls within a deletion in the read then hardClipBothEnds would cut the right tail first including the entire deletion, then fail to cut the left tail because there would not be any bases there anymore. Fixed.
The base qualities of a consensus reads are now the average quality of the bases forming the consensus base (most common base) and the consensus quality tag now carry an array with the counts of each base in the consensus. This should increase file size but improve calling sensitivity/specificity.
* Includes tests that include HardClip to Read and Reference Coords.
* Changed ReadUtils.HardClipByReferenceCoordinates from private to protected to allow for testing
when hard clipping the right tail of a read falls inside a deletion, clipping should fall back to the last base before the deletion to follow the ReadClipper's contract.
* RR will now compress reads that span across multiple intervals correctly and output them in the correct order.
* Fixed bug in getReadCoordinateForReferenceCoordinate where if the requested reference coordinate fell inside a deletion in the read the read would be clipped up to one element past the deletion.
-- resulted in massive code cleanup
-- GdA will integrate his new banded algorithm here
-- Removed: DO_CONTEXT_DEPENDENT_PENALTIES, GET_GAP_PENALTIES_FROM_DATA, INDEL_RECAL_FILE, dovit, GSA_PRODUCTION_ONLY
-- UnitTests for key functions on reduced reads
-- PileupElement calls static functions in ReadUtils
-- Simple routine that takes a reduced read and fills in its quals with its reduced qual
b) Change md5 to reflect records that are now merged correctly.
c) Change unit merge alleles test to reflect the fact that a null non-variant vc object is not valid and not supported because there's no way to codify such object in a vcf. The code correctly converts this to a non-variant single-base event with whatever the reference is at that location.
With the current implementation, a read cannot start with a deletion or an insertion. Maybe this will change in the future, but for now, chop the leading insertion off.
b) First reimplementation of new vc merger of different types. Previous version did it in two steps, first merging all vc's per type and then trying to see if resulting vc's would be merged if alleles of one type were a subset of another, but this won't work when uniquifying genotypes since sample names would be messed up and GT sample names wouldn't match VC sample names. Now, it's actually simpler: when splitting vc's by type before merging, we check for alleles of one vc being a subset of alleles of vc of another type and if so we put them together in same list.
* Deletions now count as hard clipped bases in order to recover the original alignment start of a clipped read.
* Insertions do not count as hard clipped bases for the same reason.
* This created a bug in the previous cigar cleaning function. Fixed.
-We now assign a functional class (nonsense, missense, silent, or none) to each SnpEff effect, and add a
SNPEFF_FUNCTIONAL_CLASS annotation to the INFO field of the output VCF.
-Effects are now prioritized according to both biological impact and functional class, instead of impact only.
-Many of SnpEff's "low-impact" effects are now classified as "modifiers" with lower priority than every
other effect. This includes such "effects" as DOWNSTREAM, UPSTREAM, INTRON, GENE, EXON, and others that
really describe the location of the variant rather than its biological effect.
This code will be short-lived (likely 1.2-only), as the next version of SnpEff will include most of these
features directly.
Checking this change into Stable+Unstable instead of Unstable because the current functional class stratification
in VariantEval is basically broken and urgently needs to be fixed for production purposes.
if soft clipped bases were after a hard clipped section of the read, the hard clip was clipping the left soft clip tail as if it were a right tail. Mayhem.
* Hard clipped Cigar now includes all insertions that were hard clipped and not the deletions.
* The alignment start is now recalculated according to the new hard clipped cigar representation
Big (but not major) cleanup of code in ILG - mostly excising the old likelihood model
Activated the early-abort check for ILG. I think it should be better this way.
Be careful when using this - if you're writing a bam file it will be potentially written out of order (since the previous alignment start was at the M, not the S).
Pre-softclipped reads (with high qual) are a complicated event to deal with in the Reduced Reads environment. I chose to hard clip them out for now and added a todo item to bring them back on in the future, perhaps as a variant region.
-- Old code required qual to be <64, which isn't strictly necessary. Now uses the Picard SAMUtils.MAX_PHRED_SCORE constant
-- Unittest to enforce this behavior
-- Now handles multiple records at a site, so that you don't see records like set=dbsnp-dbsnp-dbsnp when combining something with dbsnp
-- Proper handling of ids. If you are merging files with multiple ids for the same record, the ids are merged into a comma separated list
This change is urgently required for production, which is why it's going into Stable+Unstable
instead of just Unstable.
The keys for the SnpEff version and command header lines in the VCF file output by
VariantAnnotator (OriginalSnpEffVersion and OriginalSnpEffCmd) are intentionally
different from the keys for those same lines in the SnpEff output file (SnpEffVersion
and SnpEffCmd), so that output files from VariantAnnotator won't be confused
with output files from SnpEff itself.
-- Previously, on the fly indices didn't have dictionary set on the fly, so the GATK would read, add dictionary, and rewrite the index. This is now fixed, so that the on the fly index contains the reference dictionary when first written, avoiding the unnecessary read and write
-- Added a GenomeAnalysisEngine and Walker function called getMasterSequenceDictionary() that fetches the reference sequence dictionary. This can be used conveniently everywhere, and is what's written into the Tribble index
-- Refactored tribble index utilities from RMDTrackBuilder into IndexDictionaryUtils
-- VCFWriter now requires the master sequence dictionary
-- Updated walkers that create VCFWriters to provide the master sequence dictionary
Now the functions getRefCoordSoftUnclippedStart and getRefCoordSoftUnclippedEnd will return getUnclippedStart if the read is all contained within an insertion. Updated the contracts accordingly. This should give the same behavior as the GenomeLocParser now.
-- No functional changes (my algorithm wouldn't work)
-- Major structural cleanup (returning more basic data structures that allow us to development new algorithm)
-- Unit tests for the efficiency of interval partitioning
The ClippingOp clip cigar function would run into a endless loop if the parameter were out of the reads range, I stopped the bug.
* There is no check to make sure the read coordinate are covered by the read though
When Hard clipping to interval, I added a check for deletions.
