-- Compares performance across a bunch of common operations with GATK 1.3 version of VariantContext and GATK 1.4
-- 1.3 VC and associated utilities copied wholesale into test directory under v13
compressed the representation of the reduce reads counts by offset results in 17% average compression in final BAM file size.
Example compression -->
from : 10, 10, 11, 11, 12, 12, 12, 11, 10
to: 10, 0, 1, 1,2, 2, 2, 1, 0
-- I have no idea why I named this InferredGeneticContext, a totally meaningless term
-- Renamed to CommonInfo.
-- Made package protected, as no one should use this outside of VariantContext and Genotype
-- UGEngine was using IGC constant, but it's now using the public one in VariantContext.
-- Enables further sophisticated optimizations, as this class can be smarter about storing the data and will directly support operations like subset to samples
-- All instances in the gatk that used Map<String, Genotype> now use GenotypeMap type.
-- Amazingly, there were many places where HashMap<String, Genotype> is used, so that the order of the genotypes is technically undefined and could be dangerous. Now everything uses GenotypeMap with a specific ordering of samples (by name)
-- Integrationtests updated and all pass
-- This is a more convenient accesssor than subContextOfGenotypes, represents nearly all of the use cases of the former function, and potentially can be implemented more efficiently.
The primary use of this stratification is to provide a mechanism to divide asssessment of a call set up by whether a variant overlaps an interval or not. I use this to differentiate between variants occurring in CCDS exons vs. those in non-coding regions, in the 1000G call set, using a command line that looks like:
-T VariantEval -R human_g1k_v37.fasta -eval 1000G.vcf -stratIntervals:BED ccds.bed -ST IntervalStratification
Note that the overlap algorithm properly handles symbolic alleles with an INFO field END value. In order to safely use this module you should provide entire contigs worth of variants, and let the interval strat decide overlap, as opposed to using -L which will not properly work with symbolic variants.
Minor improvements to create() interval in GenomeLocParser.
