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.
-- The logic for determining active regions was a bit broken in the HC when intervals were used in the system
-- TraverseActiveRegions now uses the AllLocus view, since we always want to see all reference sites, not just those covered. Simplifies logic of TAR
-- Non-overlapping intervals are always treated as separate objects for determing active / inactive state. This means that each exon will stand on its own when deciding if it should be active or inactive
-- Misc. cleanup, docs of some TAR infrastructure to make it safer and easier to debug in the future.
-- Committing the SingleExomeCalling script that I used to find this problem, and will continue to use in evaluating calling of a single exome with the HC
-- Make sure to get all of the reads into the set of potentially active reads, even for genomic locations that themselves don't overlap the engine intervals but may have reads that overlap the regions
-- Remove excessively expensive calls to check bases are upper cased in ReferenceContext
-- Update md5s after a lot of manual review and discussion with Ryan
-- 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
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 *
