-- Instead issue a warning when a large (>1MB) record is encountered
-- Optimized ref.getBytes()[i] => (byte)ref.charAt(i), which avoids an implicit O(n) allocation each iteration through computeReverseClipping()
-- samtools can emit alleles where the ref is 42M Ns and this caused the GATK (via tribble) to hang in several places.
-- Tribble was updated so we actually could read the line properly (rev. to 51 here).
-- Still the parsing algorithms in the GATK aren't happy with such a long allele. Instead of optimizing the code around an improper use case I put in a limit of 2^16 bp for any allele, and throw a meaningful exception when encountered.
-- 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
-- With our GenotypesContext class we can naturally create a LazyGenotypesContext subclass that does the on-demand loading.
-- This new class was replaced all of the old, complex functionality
-- Better still, there were many cases were the genotypes were being loaded unnecessarily, resulting in efficiency. This was detected because some of the integration tests changed as the genotypes were no longer being parsing unnecessarily
-- Misc. bug fixes throughout the system
-- Bug fixes for PhaseByTransmission with new GenotypesContext
-- 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.
-- 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
-- A bit of code cleanup in VCFUtils
-- VariantEval table to create 1000G Phase I variant summary table
-- First version of 1000G Phase I summary table Qscript
Table codec now yells at users for not providing a HEADER with the table - parsing tables without a header line was causing the first line of the file to be eaten.
Table feature now has a toString method.
These are minor bug fixes.
-- Previously, on the fly indices didn't have dictionary set on the fly, so the GATK would read, add dictionary, and rewrite the index. This is now fixed, so that the on the fly index contains the reference dictionary when first written, avoiding the unnecessary read and write
-- Added a GenomeAnalysisEngine and Walker function called getMasterSequenceDictionary() that fetches the reference sequence dictionary. This can be used conveniently everywhere, and is what's written into the Tribble index
-- Refactored tribble index utilities from RMDTrackBuilder into IndexDictionaryUtils
-- VCFWriter now requires the master sequence dictionary
-- Updated walkers that create VCFWriters to provide the master sequence dictionary
-Rewrote SnpEff support in VariantAnnotator to support the latest SnpEff release (version 2.0.2)
-Removed support for SnpEff 1.9.6 (and associated tribble codec)
-Will refuse to parse SnpEff output files produced by unsupported versions (or without a version tag)
-Correctly matches ref/alt alleles before annotating a record, unlike the previous version
-Correctly handles indels (again, unlike the previous version
