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
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.
* Generalized the concept of a synthetic read to cread both running consensus and a synthetic reads of filtered data.
* Synthetic reads can now have deletions (but not insertions)
* New reduced read tag for filtered data synthetic reads *(RF)*
* Sliding window header now keeps information of consensus and filtered data
* Synthetic reads are created simultaneously, new functionality is controlled internally by addToSyntheticReads
-- 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.
when constructing a GATKSAMRecord from scratch, we should set "mRestOfBinaryData" to null so the BAMRecord doesn't try to retrieve missing information from the non-existent bam file.
The GATK engine will now provide a GATKSAMRecord to all tools which incorporates the functionality used by the GATK to the bam file (ReadGroups, Reduced Reads, ...).
* No tools should create SAMRecord anymore, use GATKSAMRecord instead *
-- scatterLocusIntervals master utility
-- Moved around some general functionality from GenomeLocSortedSet to GenomeLoc
-- Util function for reversing a list (List<T> -> List<T>, unlike Collections version)
-- DoC is PartitionType.INTERVAL
-- Significant unit tests on new functionality (all passing)
-- Ready for real-world testing, as soon as I can get LocusScatterFunction.scala to actually work
Bases that were excluded for MQ and BQ filters are now contributing to the MQ RMS (but not to consensus base counts and variant/not variant region triggers).
Reducing the reference bases to '=' results in an extra compression of 13% on average. The GATK is not ready to handle files with '=' bases, and the decision was to implement this a an engine support, not a part of ReduceReads.
