-- 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.
