--handle entirely missing GT in a sample in decodeGenotypeAlleles
--Create MAX_ALLELES_IN_GENOTYPES constant in BCF2Utils, and extracted its use inline from the code
-- Generalized genotype writing code to handle ploidy != 2 and variable ploidy among samples
-- Remove special case inline treatment of case where all samples have no GT field values, and moved this into calcVCFGenotypeKeys
-- Removed restriction on getPloidy requiring ploidy > 1. It's logically find to return 0 for a no called sample
-- getMaxPloidy() in VC that does what it says
-- Support for padding / depadding of generic genotype fields
-- fixed final bugs with PL encoding / decoding
-- Ready for testing by other members of the group
-- Current performance numbers aren't so great, but they will improve in the next phase of BCF2 optimizations
-- Fixed a nasty bug in the filter field
-- Not that some (many?) GATK tools won't work with BCF because they internally assume values are Strings not their true types
Read 1500 genotypes file in VCF -> VCF : 11 seconds
Read 1500 genotypes file in VCF -> BCF : 9.5 seconds
VariantEval 1500 genotypes file in VCF : 3 seconds
VariantEval 1500 genotypes file in BCF : 3 seconds
-- Trivial import changes in some walkers
-- SelectVariants has a new hidden mode to fully decode a VCF file
-- DepthPerAlleleBySample (AD) changed to have not UNBOUNDED by A type, which is actually the right type
-- GenotypeLikelihoods now implements List<Double> for convenience. The PL duality here is going to be removed in a subsequent commit
-- BugFixes in BCF2Writer. Proper handling of padding. Bugfix for nFields for a field
-- padAllele function in VariantContextUtils
-- Much better tests for VariantContextTestProvider, including loading parts of dbSNP 135 and the Phase II 1000G call set with genotypes to test encoding / decoding of fields.
-- List<String> is converted inside of the codec to a collapsed string, and exploded in the decoder.
-- Unified the type conversion code in BCFWriter to simply the mapping from VCF type => BCF type and special value recoding
-- Code cleanup and renaming
-- Convenience routine for creating alleles from strings of bases
-- Convenience constructor for VCFFilterHeader line whose description is the same as name
-- VariantContextTestProvider creates all sorts of types of VariantContexts for testing purposes. Can be reused throughtout code for BCF, VCF, etc.
-- Created basic BCF2WriterCodec tests that consumes VariantContextTestProvider contexts, writes them to disk with BCF2 writer, and checks that they come back equals to the original VariantContexts. Actually worked for some complex tests in the first go
-- Added VCFHeader() constructor that makes an empty header, and updated VariantRecalibrator to use it
-- Update build.xml to build vcf.jar with updated paths and bcf2 support.
-- Moved VCF and BCF writers to variantcontext.writers
-- Updated vcf.jar build path
-- Refactored VCFWriter and other code. Now the best (and soon to be only) way to create these files is through a factory method called VariantContextWriterFactory. Renamed the general VCFWriter interface to VariantContextWriter which is implemented by VCFWriter and BCF2Writer.
-- Refactored VCF writers into vcf.writers package
-- Moved BCF2Writer to bcf2.writer
-- Updates to all of the walkers using VCFWriter to reflect new packages
-- A large number of files had their headers cleaned up because of this as well
-- Update code to name new, more general decodeSingleValue
-- Update MISSING_VALUE constants to be 0xFFFFFF80 vs. 0x00000080 as these are equivalent for a byte and handle the two complement cast from byte to int
-- Fix decoding of byte and short values which were screwing up missing values
-- Code cleanup in decoder
-- Generalize bestIntegerType function
-- Handle the encoding of boolean FLAG fields
-- Test the encoding of vectors of values
-- BCF2 encoder and BCF2 decoder are now fully tested, and are working correctly.
-- Code cleanup and reorganization to fix bugs encountered during testing.
-- Decoder is a low-level reader of underlying data from a BCF2 encoded stream
-- Codec uses the decoder to build a VC from the stream
-- Separation key for upcoming UnitTest framework that will ensure correctness of low-level decoder / encoder before optimization of the encoder / decoder starts
-- Restructured code to separate the MISSING value in java (currently everywhere a null) from the byte representation on disk (an int).
-- Now handles correctly MISSING qual fields
-- Refactored setting of contigs from VCFWriterStub to VCFUtils. Necessary for proper BCF working
-- Added VCFContigHeaderLine that manages the order for sorting, so we now emit contigs in the proper order.
-- Cleaned up VCFHeader operations
-- BCF now uses the right header files correctly when encoding / decoding contigs
-- Support for string dictionary at standard positions in the VCF
-- Refactored setting of contigs from VCFWriterStub to VCFUtils. Necessary for proper BCF working
-- Added VCFContigHeaderLine that manages the order for sorting, so we now emit contigs in the proper order.
-- Cleaned up VCFHeader operations
-- BCF now uses the right header files correctly when encoding / decoding contigs
-- Clean up unused tools
-- Refactored header parsing routines to make them more accessible
-- More minor header changes from Intellij
