-- This is a temporarily fix / hack to deal with the very high QD values that are generated by the haplotype caller when nearby events occur within reads. In that case, the QUAL field can be many fold higher than normal, and results in an inflated QD value. This hack projects such high QD values back into the good range (as these are good variants in general) so they aren't filtered away by VQSR.
-- The long-term solution to this problem is to move the HaplotypeCaller to the full bubble calling algorithm
-- Update md5s
- Moved AverageAltAlleleLength, MappingQualityZeroFraction and TechnologyComposition to Private
- VariantType, TransmissionDisequilibriumTest, MVLikelihoodRatio and GCContent are no longer Experimental
- AlleleBalanceBySample, HardyWeinberg and HomopolymerRun are Experimental and available to users with a big bold caveat message
- Refactored getMeanAltAlleleLength() out of AverageAltAlleleLength into GATKVariantContextUtils in order to make QualByDepth independent of where AverageAltAlleleLength lives
- Unrelated change, bundled in for convenience: made HC argument includeUnmappedreads @Hidden
- Removed unnecessary check in AverageAltAlleleLength
ALL GATK DEVELOPERS PLEASE READ NOTES BELOW:
I have updated the @Output annotation to behave differently and to include a 'defaultToStdout' tag.
* The 'defaultToStdout' tags lets walkers specify whether to default to stdout if -o is not provided.
* The logic for @Output is now:
* if required==true then -o MUST be provided or a User Error is generated.
* if required==false and defaultToStdout==true then the output is assigned to stdout if no -o is provided.
* this is the default behavior (i.e. @Output with no modifiers).
* if required==false and defaultToStdout==false then the output object is null.
* use this combination for truly optional outputs (e.g. the -badSites option in AssessNA12878).
* I have updated walkers so that previous behavior has been maintained (as best I could).
* In general, all @Outputs with default long/short names have required=false.
* Walkers with nWayOut options must have required==false and defaultToStdout==false (I added checks for this)
* I added unit tests for @Output changes with David's help (thanks!).
* #resolve GSA-837
* ClippingOp updated to incorporate Ns in the hard clips.
* ReadUtils.getReadCoordinateForReferenceCoordinate() updated to account for Ns.
* Added test that covers the BQSR case we saw.
* Created GSA-856 (for Mauricio) to add lots of tests to ReadUtils.
* It will require refactoring code and not in the scope of what I was willing to do to fix this.
-"git clone" was failing intermittently with disturbing error messages about
missing certain files. Use cp -r instead.
-Add extra checks and steps to try to ensure we have a complete checkout
with no missing files.
-Turns out the Java 6 JCE crypto library (used to decrypt our AWS keys)
uses the current list of files in the java.io.tmpdir as a source of
entropy. This file list operation was prohibitively slow with a large,
shared temp directory.
-Starting with an independent, empty temp dir for each run should solve
this problem, and get rid of all/most of the test timeouts we've been
seeing.
-- Strandless GATK reads are ones where they don't really have a meaningful strand value, such as Reduced Reads or fragment merged reads. Added GATKSAMRecord support for such reads, along with unit tests
-- The merge overlapping fragments code in FragmentUtils now produces strandless merged fragments
-- FisherStrand annotation generalized to treat strandless as providing 1/2 the representative count for both strands. This means that that merged fragments are properly handled from the HC, so we don't hallucinate fake strand-bias just because we managed to merge a lot of reads together.
-- The previous getReducedCount() wouldn't work if a read was made into a reduced read after getReducedCount() had been called. Added new GATKSAMRecord method setReducedCounts() that does the right thing. Updated SlidingWindow and SyntheticRead to explicitly call this function, and so the readTag parameter is now gone.
-- Update MD5s for change to FS calculation. Differences are just minor updates to the FS
-- Code was undocumented, big, and not well tested. All three things fixed.
-- Currently not passing, but the framework works well for testing
-- Added concat(byte[] ... arrays) to utils
-script now supports a variable number of test class suffixes (eg., UnitTest,
IntegrationTest, etc.) meaning we can, for example, dispatch all unit
and integration tests at once in a single job array
-write an entry to a log file at the end of each run including the build ID,
exit status (COMPLETED or TIMED_OUT), total runtime, and time spent waiting
for farm jobs to complete
-more detailed output: print how many jobs are pending vs. running vs. done,
instead of just how many jobs are unfinished
-all errors now go to stderr rather than stdout
-Allow the default S3 put timeout of 30 seconds for GATKRunReports
to be overridden via a constructor argument, and use a timeout
of 300 seconds for tests. The timeout remains 30 seconds in all
other cases.
-Change integration tests that themselves dispatch farm jobs
into pipeline tests. Necessary because some farm nodes are
not set up as submit hosts. Pipeline tests are still run
directly on gsa4.
-Bump up the timeout for the MaxRuntimeIntegrationTest even more
(was still occasionally failing on the farm!)

* Allow RR to write its BAM to stdout by setting required=true for @Output.
* Fixed bug in sliding window where a break in coverage after a long stretch without
a variant region was causing a doubling of all the reads before the break.
* Refactored SlidingWindow.updateHeaderCounts() into 3 separate tested methods.
* Refactored polyploid consensus code out of SlidingWindow.compressVariantRegion().
-With one bsub command per job, dispatch time could vary from 2 minutes to 2 hours (!)
-By dispatching all jobs at once using a job array, this potential bottleneck
is removed
Ancient DNA sequencing data is in many ways different from modern data, and methods to analyze it need to be adapted accordingly.
Feature 1: Read adaptor trimming. Ancient DNA libraries typically have very short inserts (in the order of 50 bp), so typical Illumina libraries sequenced in, say, 100bp HiSeq will have a large adaptor component being read after the insert.
If this adaptor is not removed, data will not be aligneable. There are third party tools that remove adaptor and potentially merge read pairs, but are cumbersome to use and require precise knowledge of the library construction and adaptor sequence.
-- New walker ReadAdaptorTrimmer walks through paired end data, computes pair overlap and trims auto-detected adaptor sequence.
-- Unit tests added for trimming operation.
-- Utility walker (may be retired later) DetailedReadLengthDistribution computes insert size or read length distribution stratified by read group and mapping status and outputs a GATKReport with data.
-- Renamed MaxReadLengthFilter to ReadLengthFilter and added ability to specify minimum read length as a filter (may be useful if, as a consequence of adaptor trimming, we're left with a lot of very short reads which will map poorly and will just clutter output BAMs).
Feature 2: Unbiased site QUAL estimation: many times ancestral allele status is not known and VCF fields like QUAL, QD, GQ, etc. are affected by the pop. gen. prior at a site. This might introduce subtle biases in studies where a species is aligned against the reference of another species, so an option for UG and HC not to apply such prior is introduced.
-- Added -noPrior argument to StandardCallerArgumentCollection.
-- Added option not to fill priors is such argument is set.
-- Added an integration test.
- This was needed since samples with spaces in their names are regularly found in the picard pipeline.
- Modified the tests to account for this (removed spaces from the good tests, and changed the failing tests accordingly)
- Cleaned up the unit tests using a @DataProvider (I'm in love...).
- Moved AlleleBiasedDownsamplingUtilsUnitTest to public to match location of class it is testing (due to the way bamboo operates)
