From 7c8a1ae8929ef47fc81b8512c6c7b272e41ca8c5 Mon Sep 17 00:00:00 2001 From: Valentin Ruano-Rubio Date: Tue, 20 May 2014 18:32:03 -0400 Subject: [PATCH 1/2] Fix for SW to make double comparisons with a tolerance Stories: - https://www.pivotaltracker.com/story/show/69577868 Changes: - Added a epsilon difference tolerance in weight comparisons. Tests: - Added HaplotypeCallerIntegrationTest#testDifferentIndelLocationsDueToSWExactDoubleComparisonsFix - Updated md5 due to minor likelihood changes. - Disabled a test for PathUtils.calculateCigar since does not work and is unclear what is causing the error (needs original author input) --- .../haplotypecaller/HaplotypeResolver.java | 5 +- .../haplotypecaller/LocalAssemblyEngine.java | 8 ++- .../tools/walkers/indels/IndelRealigner.java | 6 +- ...lexAndSymbolicVariantsIntegrationTest.java | 4 +- ...plotypeCallerGenotypingEngineUnitTest.java | 11 +++- .../HaplotypeCallerIntegrationTest.java | 24 +++++++ .../haplotypecaller/graphs/PathUnitTest.java | 13 ---- ...EdgeGreedySWPairwiseAlignmentUnitTest.java | 14 ++-- .../SWPairwiseAlignmentUnitTest.java | 8 +-- .../gatk/utils/sam/CigarUtils.java | 10 +-- .../gatk/utils/smithwaterman/Parameters.java | 8 ++- .../smithwaterman/SWPairwiseAlignment.java | 64 +++++++++++++++---- .../SWPairwiseAlignmentMain.java | 2 +- .../utils/smithwaterman/SWParameterSet.java | 4 +- .../broadinstitute/gatk/utils/BaseTest.java | 3 +- .../smithwaterman/SmithWatermanBenchmark.java | 7 +- 16 files changed, 131 insertions(+), 60 deletions(-) diff --git a/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/HaplotypeResolver.java b/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/HaplotypeResolver.java index 712da91e5..ddbd5dc76 100644 --- a/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/HaplotypeResolver.java +++ b/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/HaplotypeResolver.java @@ -343,13 +343,14 @@ public class HaplotypeResolver extends RodWalker { private static final double SW_MISMATCH = -10.0; private static final double SW_GAP = -25.0; private static final double SW_GAP_EXTEND = -1.3; + private static final double SW_EPSILON = 0.00001; private void resolveByHaplotype(final ReferenceContext refContext) { final byte[] source1Haplotype = generateHaplotype(sourceVCs1, refContext); final byte[] source2Haplotype = generateHaplotype(sourceVCs2, refContext); - final SWPairwiseAlignment swConsensus1 = new SWPairwiseAlignment( refContext.getBases(), source1Haplotype, SW_MATCH, SW_MISMATCH, SW_GAP, SW_GAP_EXTEND ); - final SWPairwiseAlignment swConsensus2 = new SWPairwiseAlignment( refContext.getBases(), source2Haplotype, SW_MATCH, SW_MISMATCH, SW_GAP, SW_GAP_EXTEND ); + final SWPairwiseAlignment swConsensus1 = new SWPairwiseAlignment( refContext.getBases(), source1Haplotype, SW_MATCH, SW_MISMATCH, SW_GAP, SW_GAP_EXTEND, SW_EPSILON ); + final SWPairwiseAlignment swConsensus2 = new SWPairwiseAlignment( refContext.getBases(), source2Haplotype, SW_MATCH, SW_MISMATCH, SW_GAP, SW_GAP_EXTEND, SW_EPSILON ); // protect against SW failures if( swConsensus1.getCigar().toString().contains("S") || swConsensus1.getCigar().getReferenceLength() < 20 || diff --git a/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/LocalAssemblyEngine.java b/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/LocalAssemblyEngine.java index 2ae031f4b..d9bdc6d44 100644 --- a/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/LocalAssemblyEngine.java +++ b/protected/gatk-tools-protected/src/main/java/org/broadinstitute/gatk/tools/walkers/haplotypecaller/LocalAssemblyEngine.java @@ -188,6 +188,7 @@ public abstract class LocalAssemblyEngine { final int activeRegionStart = refHaplotype.getAlignmentStartHapwrtRef(); final ArrayList finders = new ArrayList<>(graphs.size()); + int failedCigars = 0; for( final SeqGraph graph : graphs ) { final SeqVertex source = graph.getReferenceSourceVertex(); @@ -201,10 +202,10 @@ public abstract class LocalAssemblyEngine { final KBestHaplotype kBestHaplotype = bestHaplotypes.next(); final Haplotype h = kBestHaplotype.haplotype(); if( !returnHaplotypes.contains(h) ) { - final Cigar cigar = CigarUtils.calculateCigar(refHaplotype.getBases(), h.getBases()); + final Cigar cigar = CigarUtils.calculateCigar(refHaplotype.getBases(),h.getBases()); if ( cigar == null ) { - // couldn't produce a meaningful alignment of haplotype to reference, fail quietly + failedCigars++; // couldn't produce a meaningful alignment of haplotype to reference, fail quietly continue; } else if( cigar.isEmpty() ) { throw new IllegalStateException("Smith-Waterman alignment failure.
