-We now assign a functional class (nonsense, missense, silent, or none) to each SnpEff effect, and add a
SNPEFF_FUNCTIONAL_CLASS annotation to the INFO field of the output VCF.
-Effects are now prioritized according to both biological impact and functional class, instead of impact only.
-Many of SnpEff's "low-impact" effects are now classified as "modifiers" with lower priority than every
other effect. This includes such "effects" as DOWNSTREAM, UPSTREAM, INTRON, GENE, EXON, and others that
really describe the location of the variant rather than its biological effect.
This code will be short-lived (likely 1.2-only), as the next version of SnpEff will include most of these
features directly.
Checking this change into Stable+Unstable instead of Unstable because the current functional class stratification
in VariantEval is basically broken and urgently needs to be fixed for production purposes.
-- Old code required qual to be <64, which isn't strictly necessary. Now uses the Picard SAMUtils.MAX_PHRED_SCORE constant
-- Unittest to enforce this behavior
-- Now handles multiple records at a site, so that you don't see records like set=dbsnp-dbsnp-dbsnp when combining something with dbsnp
-- Proper handling of ids. If you are merging files with multiple ids for the same record, the ids are merged into a comma separated list
This change is urgently required for production, which is why it's going into Stable+Unstable
instead of just Unstable.
The keys for the SnpEff version and command header lines in the VCF file output by
VariantAnnotator (OriginalSnpEffVersion and OriginalSnpEffCmd) are intentionally
different from the keys for those same lines in the SnpEff output file (SnpEffVersion
and SnpEffCmd), so that output files from VariantAnnotator won't be confused
with output files from SnpEff itself.
After discussing this with Mark, it seems clear that the old version of the
VariantEval FunctionalClass stratification is preferable to this version.
By reverting, we maintain backwards compatibility with legacy output files
from the old GenomicAnnotator, and can add SnpEff support later without
breaking that backwards compatibility.
This reverts commit b44acd1abd9ab6eec37111a19fa797f9e2ca3326.
This is a temporary and hopefully short-lived solution. I've modified
the FunctionalClass stratification to stratify by effect impact as
defined by SnpEff annotations (high, moderate, and low impact) rather
than by the silent/missense/nonsense categories.
If we want to bring back the silent/missense/nonsense stratification,
we should probably take the approach of asking the SnpEff author
to add it as a feature to SnpEff rather than coding it ourselves,
since the whole point of moving to SnpEff was to outsource genomic
annotation.
-Rewrote SnpEff support in VariantAnnotator to support the latest SnpEff release (version 2.0.2)
-Removed support for SnpEff 1.9.6 (and associated tribble codec)
-Will refuse to parse SnpEff output files produced by unsupported versions (or without a version tag)
-Correctly matches ref/alt alleles before annotating a record, unlike the previous version
-Correctly handles indels (again, unlike the previous version
b) More useful AC,AF logging in VariantsToTable with multiallelic sites: instead of logging comma-separated values, log max value by default. Hidden, experimental argument -logACSum to log sum of ACs instead. This is due to extreme slowness of R in parsing strings to tokens and computing max/sum itself (~100x slower than gatk).
c) Added integrationtest for new SelectVariants commands
- Ability to pass a different resident memory reservation and limits. Useful for large pileups of low pass genome data that sometimes need high -Xmx6g but usually don't exceed 2-3g in actual heap size.
- Fixed jobPriority to work for all job runners. Now must be a integer between 0 and 100- even for GridEngine- and will be mapped to the correct values.
- Passing parallel environment and job resource requests to LSF and GridEngine. Useful for passing tokens like iodine_io=1 and -pe pe_slots 8
- Refactored GridEngine JobRunner to also provide basic support for other job dispatchers with DRMAA implementations such as Torque/PBS. Should work for basic running but advanced users must pass their own jobNativeArgs from the command line or in customized QScripts until someone maps properties like jobQueue, jobPriority, residentRequest, etc. into a Torque/PBS/etc. dispatcher.
Misc updates to WholeGenomeIndelCalling.scala
Bug fix in VariantEval (may be temporary, need more investigation): if -disc option is used in sites-only vcf's then a null pointer exception is produced, caused by recent introduction of -xl_sf options.
VariantEval module CountVariants is corrected and an additional column is added so that we log mixed events and complex indels separately (before they were being conflated).
VariantEval module IndelStatistics is considerably simplified as the sample stratification was wrong and redundant, now it should work with the VE-generic Sample stratification. Several columns are renamed or removed since they're not really useful
