-- 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.
