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.
-- 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
It is outputting a VCF with the 'second best guess' for the alternate allele correctly. Annotations are added at the pool level, but may get overwritten at the lane and site level. Still need to implement the merging of the the annotations at higher levels.
Calls are now made based on the likelihood AC model. Two filters are applied: minQual and minPower. Output is now a VCF file with the variant context. It's now called the gatk's PoolCaller, no longer Replication Validation framework. Lots of testing ensue....
