-- Changes associated code throughout the codebase
-- Updated necessary (but minimal) UnitTests to reflect new behavior
-- Much better makealleles() function in VC.java that enforces a lot of key constraints in VC
-- the underlying data structure is still present, but until I decide what to do for the extensible system I've completely disabled the subsystem
-- Added code to merge Samples, so that a mostly full record can be merged with a consistent empty record. If the two records are inconsistent, an error is thrown
-- addSample() in Sample.class now invokes mergeSample() when appropriate
-- Validation types are now only STRICT or SILENT
-- Validation code implemented in SampleDBBuilder
-- Extensive unit tests for SampleDBBuilder
-- Passes significiant unit tests
-- Implicit sample creation for mom / dad when you create single samples
-- Continuing cleanup of Sample and SampleDataSource
b) Change md5 to reflect records that are now merged correctly.
c) Change unit merge alleles test to reflect the fact that a null non-variant vc object is not valid and not supported because there's no way to codify such object in a vcf. The code correctly converts this to a non-variant single-base event with whatever the reference is at that location.
b) First reimplementation of new vc merger of different types. Previous version did it in two steps, first merging all vc's per type and then trying to see if resulting vc's would be merged if alleles of one type were a subset of another, but this won't work when uniquifying genotypes since sample names would be messed up and GT sample names wouldn't match VC sample names. Now, it's actually simpler: when splitting vc's by type before merging, we check for alleles of one vc being a subset of alleles of vc of another type and if so we put them together in same list.
-We now assign a functional class (nonsense, missense, silent, or none) to each SnpEff effect, and add a
SNPEFF_FUNCTIONAL_CLASS annotation to the INFO field of the output VCF.
-Effects are now prioritized according to both biological impact and functional class, instead of impact only.
-Many of SnpEff's "low-impact" effects are now classified as "modifiers" with lower priority than every
other effect. This includes such "effects" as DOWNSTREAM, UPSTREAM, INTRON, GENE, EXON, and others that
really describe the location of the variant rather than its biological effect.
This code will be short-lived (likely 1.2-only), as the next version of SnpEff will include most of these
features directly.
Checking this change into Stable+Unstable instead of Unstable because the current functional class stratification
in VariantEval is basically broken and urgently needs to be fixed for production purposes.
