From d689f61005605b54410d1960251cb0bf9865342d Mon Sep 17 00:00:00 2001 From: Eric Banks Date: Fri, 7 Feb 2014 11:36:49 -0500 Subject: [PATCH] Fixed up some of the genotype-level annotations being propogated in the single sample HC pipeline. 1. AD values now propogate up (they weren't before). 2. MIN_DP gets transferred over to DP and removed. 3. SB gets removed after FS is calculated. Also, added a bunch of new integration tests for GenotypeGVCFs. --- .../walkers/variantutils/GenotypeGVCFs.java | 55 +++++++++++++++---- .../CombineGVCFsIntegrationTest.java | 2 +- .../GenotypeGVCFsIntegrationTest.java | 40 ++++++++++++-- .../variant/GATKVariantContextUtils.java | 30 +++++++++- 4 files changed, 111 insertions(+), 16 deletions(-) diff --git a/protected/gatk-protected/src/main/java/org/broadinstitute/sting/gatk/walkers/variantutils/GenotypeGVCFs.java b/protected/gatk-protected/src/main/java/org/broadinstitute/sting/gatk/walkers/variantutils/GenotypeGVCFs.java index 00def65c0..d2374ccb8 100644 --- a/protected/gatk-protected/src/main/java/org/broadinstitute/sting/gatk/walkers/variantutils/GenotypeGVCFs.java +++ b/protected/gatk-protected/src/main/java/org/broadinstitute/sting/gatk/walkers/variantutils/GenotypeGVCFs.java @@ -68,8 +68,7 @@ import org.broadinstitute.sting.utils.help.DocumentedGATKFeature;
