From 9dd109b79ad95fb863e419d0d6f6634a13240a15 Mon Sep 17 00:00:00 2001 From: Guillermo del Angel Date: Tue, 16 Jul 2013 11:14:48 -0400 Subject: [PATCH] Last feature request from Reich/Paavo labs: the allSitePLs feature in UG worked but not quite filled requirements. What's needed is the ability to have all 10 PLs for EVERY site, regardless of whether they are variant or not. Previous version only emitted the 10 PLs in reference sites. Problem is that, if all PLs are emitted in all sites and every single site is quad-allelic (only way to have the PLs printed out in a valid way) then the ability to filter variants and to use the INFO fields may be compromised. So, compromise solution is to go back to having biallelic PLs but emit a new FORMAT field, called APL, which has the 10 values, but all other statistics and regular PLs are computed as before. Note that integration test had to be disabled, as the BCF2 codec apparently doesn't support writing into genotype fields other than PL,DP,AD,GQ,FT and GT. --- .../SNPGenotypeLikelihoodsCalculationModel.java | 9 ++------- .../sting/gatk/walkers/genotyper/UnifiedGenotyper.java | 3 +++ .../gatk/walkers/genotyper/UnifiedGenotyperEngine.java | 1 + .../genotyper/UnifiedGenotyperIntegrationTest.java | 5 ++++- 4 files changed, 10 insertions(+), 8 deletions(-) diff --git a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/SNPGenotypeLikelihoodsCalculationModel.java b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/SNPGenotypeLikelihoodsCalculationModel.java index 360f88e51..f94baf09f 100644 --- a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/SNPGenotypeLikelihoodsCalculationModel.java +++ b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/SNPGenotypeLikelihoodsCalculationModel.java @@ -147,13 +147,6 @@ public class SNPGenotypeLikelihoodsCalculationModel extends GenotypeLikelihoodsC // if we only want variants, then we don't need to calculate genotype likelihoods if ( UAC.OutputMode == UnifiedGenotyperEngine.OUTPUT_MODE.EMIT_VARIANTS_ONLY ) return builder.make(); - // if user requires all PLs at all sites, add all possible alt alleles - else if (UAC.annotateAllSitesWithPLs) { - for ( final byte base : BaseUtils.BASES ) { - if ( base != refBase ) - alleles.add(Allele.create(base)); - } - } else // otherwise, choose any alternate allele (it doesn't really matter) @@ -199,6 +192,8 @@ public class SNPGenotypeLikelihoodsCalculationModel extends GenotypeLikelihoodsC final double[] genotypeLikelihoods = MathUtils.normalizeFromLog10(myLikelihoods, false, true); gb.PL(genotypeLikelihoods); gb.DP(sampleData.depth); + if (UAC.annotateAllSitesWithPLs) + gb.attribute(UnifiedGenotyperEngine.PL_FOR_ALL_SNP_ALLELES_KEY,GenotypeLikelihoods.fromLog10Likelihoods(MathUtils.normalizeFromLog10(allLikelihoods, false, true))); genotypes.add(gb.make()); } diff --git a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/UnifiedGenotyper.java b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/UnifiedGenotyper.java index 54fcad1df..82b93aa55 100644 --- a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/UnifiedGenotyper.java +++ b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/UnifiedGenotyper.java @@ -318,6 +318,9 @@ public class UnifiedGenotyper extends LocusWalker, Unif headerInfo.add(new VCFInfoHeaderLine(VCFConstants.REFSAMPLE_DEPTH_KEY, 1, VCFHeaderLineType.Integer, "Total reference sample depth")); } + if (UAC.annotateAllSitesWithPLs) { + headerInfo.add(new VCFFormatHeaderLine(UnifiedGenotyperEngine.PL_FOR_ALL_SNP_ALLELES_KEY, 10, VCFHeaderLineType.Integer, "Phred-scaled genotype likelihoods for all 4 possible bases regardless of whether there is statistical evidence for them.
