-Switch back to the old implementation, if needed, with --use_legacy_downsampler
-LocusIteratorByStateExperimental becomes the new LocusIteratorByState, and
the original LocusIteratorByState becomes LegacyLocusIteratorByState
-Similarly, the ExperimentalReadShardBalancer becomes the new ReadShardBalancer,
with the old one renamed to LegacyReadShardBalancer
-Performance improvements: locus traversals used to be 20% slower in the new
downsampling implementation, now they are roughly the same speed.
-Tests show a very high level of concordance with UG calls from the previous
implementation, with some new calls and edge cases that still require more examination.
-With the new implementation, can now use -dcov with ReadWalkers to set a limit
on the max # of reads per alignment start position per sample. Appropriate value
for ReadWalker dcov may be in the single digits for some tools, but this too
requires more investigation.
-- The NanoSchedule timing code (in NSRuntimeProfile) was crazy expensive, but never showed up in the profilers. Removed all of the timing code from the NanoScheduler, the NSRuntimeProfile itself, and updated the unit tests.
-- For tools that largely pass through data quickly, this change reduces runtimes by as much as 10x. For the RealignerTargetCreator example, the runtime before this commit was 3 hours, and after is 30 minutes (6x improvement).
-- Took this opportunity to improve the GATK ProgressMeter. NotifyOfProgress now just keeps track of the maximum position seen, and a separate daemon thread ProgressMeterDaemon periodically wakes up and prints the current progress. This removes all inner loop calls to the GATK timers.
-- The history of the bug started here: http://gatkforums.broadinstitute.org/discussion/comment/2402#Comment_2402
-- The previous nanoscheduler would deadlock in the case where an Error, not an Exception, was thrown. Errors, like out of memory, would cause the whole system to die. This bugfix resolves that issue
The check is performed by a Read Transformer that samples (currently set to once
every 1000 reads so that we don't hurt overall GATK performance) from the input
reads and checks to make sure that none of the base quals is too high (> Q60). If
we encounter such a base then we fail with a User Error.
* Can be over-ridden with --allow_potentially_misencoded_quality_scores.
* Also, the user can choose to fix his quals on the fly (presumably using PrintReads
to write out a fixed bam) with the --fix_misencoded_quality_scores argument.
Added unit tests.
-- Multi-allelic variants are split into their bi-allelic version, trimmed, and we attempt to provide a meaningful genotype for NA12878 here. It's not perfect and needs some discussion on how to handle het/alt variants
-- Adding splitInBiallelic funtion to VariantContextUtils as well as extensive unit tests that also indirectly test reverseTrimAlleles (which worked perfectly FYI)
-- Closes GSA-494 / Add maximum runtime for integration tests, running them in timeout thread
-- Needed to debug locking issues
-- Needed to debug excessively long running integrationtests
-- Added build.xml maximum runtime for all testng tests of 10 hours. We will ultimately fail the build if it goes on for more than 10 hours
-- The logic for determining active regions was a bit broken in the HC when intervals were used in the system
-- TraverseActiveRegions now uses the AllLocus view, since we always want to see all reference sites, not just those covered. Simplifies logic of TAR
-- Non-overlapping intervals are always treated as separate objects for determing active / inactive state. This means that each exon will stand on its own when deciding if it should be active or inactive
-- Misc. cleanup, docs of some TAR infrastructure to make it safer and easier to debug in the future.
-- Committing the SingleExomeCalling script that I used to find this problem, and will continue to use in evaluating calling of a single exome with the HC
-- Make sure to get all of the reads into the set of potentially active reads, even for genomic locations that themselves don't overlap the engine intervals but may have reads that overlap the regions
-- Remove excessively expensive calls to check bases are upper cased in ReferenceContext
-- Update md5s after a lot of manual review and discussion with Ryan
-- As one might expect, CachingIndexedFastaSequenceFile now internally upper cases the FASTA reference bases. This is now done by default, unless requested explicitly to preserve the original bases.
-- This is really the correct place to do this for a variety of reasons. First, you don't need to work about upper casing bases throughout the code. Second, the cache is only upper cased once, no matter how often the bases are accessed, which walkers cannot optimize themselves. Finally, this uses the fastest function for this -- Picard's toUpperCase(byte[]) which is way better than String.toUpperCase()
-- Added unit tests to ensure this functionality works correct.
-- Removing unnecessary upper casing of bases in some core GATK tools, now that RefContext guarentees that the reference bases are all upper case.
-- Added contracts to ensure this is the case.
-- Remove a ton of sh*t from BaseUtils that was so old I had no idea what it was doing any longer, and didn't have any unit tests to ensure it was correct, and wasn't used anywhere in our code
-- Providing this optional argument -maxRuntime (in -maxRuntimeUnits units) causes the GATK to exit gracefully when the max. runtime has been exceeded. By cleanly I mean that the engine simply stops at the next available cycle in the walker as through the end of processing had been reached. This means that all output files are closed properly, etc.
-- Emits an info message that looks like "INFO 10:36:52,723 MicroScheduler - Aborting execution (cleanly) because the runtime has exceeded the requested maximum 10.0000 s". Otherwise there's currently no way to differentiate a truly completed run from a timelimit exceeded run, which may be a useful thing for a future update
-- Resolves GSA-630 / GATK max runtime to deal with bad LSA calling?
-- Added new JIRA entry for Ami to restart chr1 macarthur with this argument set to -maxRuntime 1 -maxRuntimeUnits DAYS to see if we can do all of chr1 in one weekend.
