-User must provide a mapping file via new --sample_rename_mapping_file argument.
Mapping file must contain a mapping from absolute bam file path to new sample name
(format is described in the docs for the argument).
-Requires that each bam file listed in the mapping file contain only one sample
in their headers (they may contain multiple read groups for that sample, however).
The engine enforces this, and throws a UserException if on-the-fly renaming is
requested for a multi-sample bam.
-Not all bam files for a traversal need to be listed in the mapping file.
-On-the-fly renaming is done as the VERY first step after creating the SAMFileReaders
in SAMDataSource (before the headers are even merged), to prevent possible consistency
issues.
-Renaming is done ONCE at traversal start for each SAMReaders resource creation in the
SAMResourcePool; this effectively means once per -nt thread
-Comprehensive unit/integration tests
Known issues: -if you specify the absolute path to a bam in the mapping file, and then
provide a path to that same bam to -I using SYMLINKS, the renaming won't
work. The absolute paths will look different to the engine due to the
symlink being present in one path and not in the other path.
GSA-974 #resolve
-Two SAMReaderIDs that pointed at the same underlying bam file through
a relative vs. an absolute path were not being treated as equal, and
had different hash codes. This was causing problems in the engine, since
SAMReaderIDs are often used as the keys of HashMaps.
-Fix: explicitly use the absolute path to the encapsulated bam file in
hashCode() and equals()
-Added tests to ensure this doesn't break again
* ReadTransformers can say they must be first, must be last, or don't care.
* By default, none of the existing ones care about ordering except BQSR (must be first).
* This addresses a bug reported on the forum where BAQ is incorrectly applied before BQSR.
* The engine now orders the read transformers up front before applying iterators.
* The engine checks for enabled RTs that are not compatible (e.g. both must be first) and blows up (gracefully).
* Added unit tests.
-- Active regions are created as normal, but they are split and trimmed to the engine intervals when added to the traversal, if there are intervals present.
-- UnitTests for ActiveRegion.splitAndTrimToIntervals
-- GenomeLocSortedSet.getOverlapping uses binary search to efficiently in ~ log N time find overlapping intervals
-- UnitTesting overlap function in GenomeLocSortedSet
-- Discovered fundamental implementation bug in that adding genome locs out of order (elements on 20 then on 19) produces an invalid GenomeLocSortedSet. Created a JIRA to address this: https://jira.broadinstitute.org/browse/GSA-775
-- Constructor that takes a collection of genome locs now sorts its input and merges overlapping intervals
-- Added docs for the constructors in GLSS
-- Update HaplotypeCaller MD5s, which change because ActiveRegions are now restricted to the engine intervals, which changes slightly the regions in the tests and so the reads in the regions, and thus the md5s
-- GenomeAnalysisEngineUnitTest needs to provide non-null genome loc parser
* Did not touch archived walkers... those can be named whatever.
* Kept abstract classes that end in Walker untouched (e.g. LocusWalker, ReadWalker, ...)
* Renamed a few inner classes due to conflict when stripping off Walker from their outer classes: ContigStats, FlagStats and FastaStats.
Updated HSP to use new padding arguments instead of flank intervals file, plus latest QC evals.
IntervalUtils return unmodifiable lists so that utilities don't mutate the collections.
Added a JavaCommandLineFunction.javaGCThreads option to test reducing java's automatic GC thread allocation based on num cpus.
Added comma to list of characters to convert to underscores in GridEngine job names so that GE JSV doesn't choke on the -N values.
JobRunInfo handles the null done times when jobs crash with strange errors.
