-- Created a ReadRecalibrationInfo class that holds all of the information (read, base quality vectors, error vectors) for a read for the call to updateDataForRead in RecalibrationEngine. This object has a restrictive interface to just get information about specific qual and error values at offset and for event type. This restrict allows us to avoid creating an vector of byte 45 for each read to represent BI and BD values not in the reads. Shaves 5% of the runtime off the entire code.
-- Cleaned up code and added lots more docs
-- With this commit we no longer have much in the way of low-hanging fruit left in the optimization of BQSR. 95% of the runtime is spent in BAQing the read, and updating the RecalData in the NestedIntegerArrays.
-- Update SAMDataSource so that the merged header contains GATKSAMReadGroupRecord
-- Now getting the NGSPlatform for a GATKSAMRecord is actually efficient, instead of computing the NGS platform over and over from the PL string
-- Updated a few places in the code where the input argument is actually a GATKSAMRecord, not a SAMRecord for type safety
This is an intermediate commit so that there is a record of these changes in our
commit history. Next step is to isolate the test classes as well, and then move
the entire package to the Picard repository and replace it with a jar in our repo.
-Removed all dependencies on org.broadinstitute.sting (still need to do the test classes,
though)
-Had to split some of the utility classes into "GATK-specific" vs generic methods
(eg., GATKVCFUtils vs. VCFUtils)
-Placement of some methods and choice of exception classes to replace the StingExceptions
and UserExceptions may need to be tweaked until everyone is happy, but this can be
done after the move.
this introduced a bug in reduce reads by de-activating it's hard clipping of the out of bounds soft-clips (specially in the MT).
DEV-322 #resolve #time 4m
This reverts commit 42acfd9d0bccfc0411944c342a5b889f5feae736.
The check is performed by a Read Transformer that samples (currently set to once
every 1000 reads so that we don't hurt overall GATK performance) from the input
reads and checks to make sure that none of the base quals is too high (> Q60). If
we encounter such a base then we fail with a User Error.
* Can be over-ridden with --allow_potentially_misencoded_quality_scores.
* Also, the user can choose to fix his quals on the fly (presumably using PrintReads
to write out a fixed bam) with the --fix_misencoded_quality_scores argument.
Added unit tests.
-- Previously these core progress metering functions were all in TraversalEngine, and available to subclasses like TraverseLoci via inheritance. The problem here is that the upcoming data threads x cpu threads parallelism requires one master copy of the progress metering shared among all traversals, but multiple instantiations of traverse engines themselves.
-- Because the progress metering code has horrible anyway, I've refactored and vastly cleaned up and simplified all of these capabilities into TraversalProgressMeter class. I've simplified down the classes it uses to work (STILL SOME TODOs in there) so that it doesn't reach into the core GATK engine all the time. It should be possible to write some nice tests for it now. By making it its own class, it can protect itself from multi-threaded access with a single synchronized printProgress function instead of carrying around multiple lock objects as before
-- Cleaned up the start up of the progress meter. It's now handled when the meter is created, so each micro scheduler doesn't have to deal with proper initialization timing any longer
-- Simplified and made clear the interface for shutting down the traversal engines. There's no a shutdown method in TraversalEngine that's called once by the MicroScheduler when the entire traversing in over. Nano traversals now properly shut down (was subtle bug I undercovered here). The printing of on traversal done metering is now handled by MicroScheduler
-- The MicroScheduler holds the single master copy of the progress meter, and doles it out to the TraversalEngines (currently 1 but in future commit there will be N).
-- Added a nice function to GenomeAnalysisEngine that returns the regions we will be processing, either the intervals requested or the whole genome. Useful for progress meter but also probably for other infrastructure as well
-- Remove a lot of the sh*ting Bean interface getting and setting in MicroScheduler that's no longer useful. The generic bean is just a shell interface with nothing in it.
-- By removing a lot of these bean accessors and setters many things are now final that used to be dynamic.
-Off by default; engine fork isolates new code paths from old code paths,
so no integration tests change yet
-Experimental implementation is currently BROKEN due to a serious issue
involving file spans. No one can/should use the experimental features
until I've patched this issue.
-There are temporarily two independent versions of LocusIteratorByState.
Anyone changing one version should port the change to the other (if possible),
and anyone adding unit tests for one version should add the same unit tests
for the other (again, if possible). This situation will hopefully be extremely
temporary, and last only until the experimental implementation is proven.
-- Moved most of BQSR classes (which are used throughout the codebase) to utils.recalibration. It's better in my opinion to keep commonly used code in utils, and only specialized code in walkers. As code becomes embedded throughout GATK its should be refactored to live in utils
-- Removed unncessary imports of BQSR in VQSR v3
-- Now ready to refactor QualQuantizer and unit test into a subclass of RecalDatum, refactor unit tests into RecalDatum unit tests, and generalize into hierarchical recal datum that can be used in QualQuantizer and the analysis of adaptive context covariate
-- Update PluginManager to sort the plugins and interfaces. This allows us to have a deterministic order in which the plugin classes come back, which caused BQSR integration tests to temporarily change because I moved my classes around a bit.
When hard-clipping predict when the read is going to be fully hard clipped to the point where only soft/hard-clips are left in the read and preemptively eliminate the read before the SAMRecord mathematics on malformed cigars kills the GATK.
* Sites with more soft clipped bases than regular will force-trigger a variant region
* No more unclipping/reclipping, RR machinery now handles soft clips natively.
* implemented support for base insertion and base deletion quality scores in synthetic and regular reads.
* GATKSAMRecord clone() now creates a fresh object for temporary attributes if one is present.
note: SAMRecords create a shallow copy of the tempAttribute object which was causing multiple reads (that came from the same read) to have their temporary attributes modified by one another inside reduce reads. Beware, if you're not using GATKSAMRecord!
* Re-wrote the sliding window approach to allow the variant region not to clip the reads that overlap it.
* Updated consensus to include only reads that were not passed on by the variant region, header counts are updated on the fly to avoid recompute
* Added soft clipped bases to ReduceReads analysis by unclipping high quality soft-clips then re-clipping after reduce reads
* Updated all integration tests
The GATK -L unmapped is for GenomeLocs with SAMRecord.NO_ALIGNMENT_REFERENCE_NAME, not SAMRecord.getReadUnmappedFlag()
Previously unmapped flag reads in the last bin were being printed while also seeking for the reads without a reference contig.
