Returns true iff VC is an non-complex indel where every allele represents an expansion or
contraction of a series of identical bases in the reference.
The logic of this function is pretty simple. Take all of the non-null alleles in VC. For
each insertion allele of n bases, check if that allele matches the next n reference bases.
For each deletion allele of n bases, check if this matches the reference bases at n - 2 n,
as it must necessarily match the first n bases. If this test returns true for all
alleles you are a tandem repeat, otherwise you are not. Note that in this context n is the
base differences between the ref and alt alleles
-- Now properly handles the case where a sample isn't present (no longer adds a null to the genotypes list)
-- Fix for logic failure where if the number of requested samples equals the number of known genotypes then all of the records were returned, which isn't correct when there are missing samples.
-- Unit tests added to handle these cases
-- Now you provide a LazyParsing object
-- LazyGenotypesContext now knows nothing about the VCF parser itself. The parser holds all of the necessary data to parse the VCF genotypes when necessarily, and the LGC only has a pointer to this object
-- Using new interface added LazyGenotypesContext to unit tests with a simple lazy version
-- Deleted VCFParser interface, as it was no longer necessary
-- We should no longer have md5s changing because of hashmaps changing their sort order on us
-- Added GenotypeLikelihoodsUnitTests
-- Refactored ExactAFCaclculation to put the PL -> QUAL calculation in the GenotypeLikelihoods class to avoid the code copy.
-- New approach to making VariantContexts modeled on StringBuilder
-- No more modify routines -- use VariantContextBuilder
-- Renamed isPolymorphic to isPolymorphicInSamples. Same for mono
-- getChromosomeCount -> getCalledChrCount
-- Walkers changed to use new VariantContext. Some deprecated new VariantContext calls remain
-- VCFCodec now uses optimized cached information to create GenotypesContext.
-- Major change to how chromosomeCounts is computed. Now NO_CALL alleles are always excluded. So ChromosomeCounts(A/.) is 1, the previous result would have been 2.
-- Naming changes for getSamplesNameInOrder()
-- 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
-- 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
-- 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
classloading of bcel*.jar/ant-apache-bcel*.jar. Switching instead to manually
specifying a minimal set of packages/classes to include in the vcf.jar via
build.xml, and adding a unit test which creates a limited classloader
only aware of vcf.jar and tribble.jar and tries to use it to load the core
classes in the vcf jar.
Hopefully third time's the charm.
