* 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
