Also, fixes to large-scale validation script: lower -minIndelFrac threshold or else we'll kill most indels since default 0.25 is too high for pools, fix also VE stratifications and add one VE run where eval=1KG, comp=pool data and AC stratification based on 1KG annotation
a) Connect picard outputs with @Output
b) Do QC by default and correct picard path in instances.
c) EXPERIMENTAL: bump up numThreads to 8 by default and see what happens
DEV-155 #resolve #time 1m
The old BaseRecalibrator walker is and never will be thread-safe, since it's a
LocusWalker that uses read attributes to track state.
ONLY the newer DelocalizedBaseRecalibrator is believed likely to be thread-safe
at this point. It is safe to run the DelocalizedBaseRecalibrator with -nct > 1
for testing purposes, but wait for further testing to be done before using it
for production purposes in multithreaded mode.
The ReadGroupCovariate class was not thread-safe. This led to horrible race conditions
in multithreaded runs of the BQSR where (for example) the same read group could get
inserted into the reverse lookup table twice with different IDs.
Should fix the intermittent crash reported in GSA-492.
-With this change, BQSR performance scales properly by thread rather
than gaining nothing from additional threads.
-Benefits are seen when using either -nt (HierarchicalMicroScheduler) or -nct
(NanoScheduler)
-Removes high-level locks in the recalibration engines and NestedIntegerArray
in favor of maximally-granular locks on and around manipulation of the leaf
nodes of the NestedIntegerArray.
-NestedIntegerArray now creates all interior nodes upfront rather than on
the fly to avoid the need for locking during tree traversals. This uses
more memory in the initial part of BQSR runs, but the BQSR would eventually
converge to use this memory anyway over the course of a typical run.
IMPORTANT NOTE: This does not mean it's safe to run the old BaseRecalibrator
walker with multiple threads. The BaseRecalibrator walker is and will never be
thread-safe, as it's a LocusWalker that uses read attributes to track
state information. ONLY the newer DelocalizedBaseRecalibrator can be made
thread-safe (and will hopefully be made so in my subsequent commits). This
commit addresses performance, not correctness.
-- Resolves issue GSA-515 / Nanoscheduler GSA-605 / Seems that -nct may deadlock as not reproducible
-- It seems that it's not an input error problem (or at least cannot be provoked with unit tests)
-- I'll keep an eye on this later
In addition to outputs, inputs are passed to QStatusMessenger.done()
CloneFunction.cloneIndex has a new CloneFunction.cloneCount companion useful for display purposes.
Bringing in the following relevant changes:
* Fixes the indel realigner N-Way out null pointer exception DEV-10
* Optimizations to ReduceReads that bring the run time to 1/3rd.

b) New interval/bait sets with corrected header for decoy contig in b37
c) New metadata file for test fastqs
d) Updated test fastqs as previous version was generated with bad intervals
-- Included logic to only add priors for alleles with sufficient evidence to be called polymorphic. If no alleles are poly make sure to add priors of first allele
-- There's been no report of problems with the nano scheduled version of TraverseLoci and TraverseReads, so I'm removing the old versions since they are no longer needed
-- Removing unnecessary intermediate base classes
-- GSA-515 / Nanoscheduler GSA-549 / https://jira.broadinstitute.org/browse/GSA-549
-- Updated StandardCallerArgumentCollection to remove MaxAltAllelesForIndels. Previous argument is deprecated with meaningful doc message for people to use maxAltAlleles
-- All constructores, factory methods, and test builders and their users updated to provide just a single argument
-- Updating MD5s for integration tests that change due to genotyping more alleles
-- Adding more alleles to genotyping results in slight changes in the QUAL value for multi-allelic loci where one or more alleles aren't polymorphic. That's simply due to the way that alternative hypotheses contribute as reference evidence against each true allele. The effect can be large (new qual = old qual / 2 in one case here).
-- If we want more precision in our estimates we could decide (Eric, should we discuss?) to actually separately do a discovery phase in the genotyping, eliminate all variants not considered polymorphic, and then do a final round of calling to get the exact QUAL value for only those that are segregating. This would have the value of having the QUAL stay constant as more alleles are genotyped, at the cost of some code complexity increase and runtime. Might be worth it through
-- Created a JIRA ticket https://jira.broadinstitute.org/browse/GSA-623 for Guillermo to look at the differences as the multi-allelic nature of many sites seems to change with the new more protected infrastructure. This may be due to implementation issues in the pooled caller, problems with my interface, or could be a genuine improvement.
-- This is no longer a core GATK activity, and the tests need to run for so long (2 min each) that it's just too painful to run them. Should be re-eabled if we come to care about this capability again, or if we can run these tests all in parallel in the future.
-- The old way of overloading constructors and calling super didn't work (might have been a consequence of merge). This is the right way to do the copy constructor with the call to super()
