Out of curiosity, why does Picard's IndexedFastaSequenceFile allow one to query for start position 0? When doing so, that base is a line feed (-1 offset to the first base in the contig) which is an illegal base (and which caused me no end of trouble)...
-- As one might expect, CachingIndexedFastaSequenceFile now internally upper cases the FASTA reference bases. This is now done by default, unless requested explicitly to preserve the original bases.
-- This is really the correct place to do this for a variety of reasons. First, you don't need to work about upper casing bases throughout the code. Second, the cache is only upper cased once, no matter how often the bases are accessed, which walkers cannot optimize themselves. Finally, this uses the fastest function for this -- Picard's toUpperCase(byte[]) which is way better than String.toUpperCase()
-- Added unit tests to ensure this functionality works correct.
-- Removing unnecessary upper casing of bases in some core GATK tools, now that RefContext guarentees that the reference bases are all upper case.
-- Added contracts to ensure this is the case.
-- Remove a ton of sh*t from BaseUtils that was so old I had no idea what it was doing any longer, and didn't have any unit tests to ensure it was correct, and wasn't used anywhere in our code
-- Created public static UnifiedGenotyper.getHeaderInfo that loads UG standard header lines, and use this in tools like PoolCaller
-- Created VCFStandardHeaderLines class that keeps standard header lines in the GATK in a single place. Provides convenient methods to add these to a header, as well as functionality to repair standard lines in incoming VCF headers
-- VCF parsers now automatically repair standard VCF header lines when reading the header
-- Updating integration tests to reflect header changes
-- Created private and public testdata directories (public/testdata and private/testdata). Updated tests to use test
-- SelectHeaders now always updates the header to include the contig lines
-- SelectVariants add UG header lines when in regenotype mode
-- Renamed PHRED_GENOTYPE_LIKELIHOODS_KEY to GENOTYPE_PL_KEY
-- Bugfix in BCF2 to handle lists of null elements (can happen in genotype field values from VCFs)
-- Throw error when VCF has unbounded non-flag values that don't have = value bindings
-- By default we no longer allow writing of BCF2 files without contig lines in the header
non-static to avoid problems when multiple references are used within the same
thread (eg., during integration tests). This should kill the intermittent
IndelRealignerIntegrationTest failures.
