From 365f1d2429361ad3a3e5c6148c7569fa5dea8d63 Mon Sep 17 00:00:00 2001 From: Christopher Hartl Date: Sat, 29 Sep 2012 00:55:31 -0400 Subject: [PATCH 01/83] hmk123's error on the forum came from the reference context occasionally lacking bases needed for validating the reference bases in the variant context. (no @Window for VariantsToBinaryPed). This bugfix adresses this and other minor items: 1) ValidateVariants removed in favor of direct validation VariantContexts. Integration test added to test broken contexts. 2) Enabling indel and SV output. Still bi-allelic sites only. Integration tests added for these cases. 3) Found a bug where GQ recalculation (if a genotype has PLs but no GQ) would only happen for flipped encoding. Fixed. Integration test added. --- .../variantutils/VariantsToBinaryPed.java | 110 +++++++++++++----- .../VariantsToBinaryPedIntegrationTest.java | 45 +++++++ 2 files changed, 124 insertions(+), 31 deletions(-) diff --git a/public/java/src/org/broadinstitute/sting/gatk/walkers/variantutils/VariantsToBinaryPed.java b/public/java/src/org/broadinstitute/sting/gatk/walkers/variantutils/VariantsToBinaryPed.java index 37fc96681..b7ef85a04 100644 --- a/public/java/src/org/broadinstitute/sting/gatk/walkers/variantutils/VariantsToBinaryPed.java +++ b/public/java/src/org/broadinstitute/sting/gatk/walkers/variantutils/VariantsToBinaryPed.java @@ -1,5 +1,7 @@ package org.broadinstitute.sting.gatk.walkers.variantutils; +import org.broad.tribble.TribbleException; +import org.broadinstitute.sting.alignment.bwa.java.AlignmentMatchSequence; import org.broadinstitute.sting.commandline.*; import org.broadinstitute.sting.gatk.CommandLineGATK; import org.broadinstitute.sting.gatk.arguments.DbsnpArgumentCollection; @@ -7,19 +9,19 @@ import org.broadinstitute.sting.gatk.arguments.StandardVariantContextInputArgume import org.broadinstitute.sting.gatk.contexts.AlignmentContext; import org.broadinstitute.sting.gatk.contexts.ReferenceContext; import org.broadinstitute.sting.gatk.refdata.RefMetaDataTracker; +import org.broadinstitute.sting.gatk.walkers.Reference; import org.broadinstitute.sting.gatk.walkers.Requires; import org.broadinstitute.sting.gatk.walkers.RodWalker; +import org.broadinstitute.sting.gatk.walkers.Window; import org.broadinstitute.sting.utils.MathUtils; +import org.broadinstitute.sting.utils.Utils; import org.broadinstitute.sting.utils.codecs.vcf.VCFHeader; import org.broadinstitute.sting.utils.codecs.vcf.VCFUtils; import org.broadinstitute.sting.utils.exceptions.ReviewedStingException; import org.broadinstitute.sting.utils.exceptions.UserException; import org.broadinstitute.sting.utils.help.DocumentedGATKFeature; import org.broadinstitute.sting.utils.text.XReadLines; -import org.broadinstitute.sting.utils.variantcontext.Genotype; -import org.broadinstitute.sting.utils.variantcontext.GenotypeLikelihoods; -import org.broadinstitute.sting.utils.variantcontext.VariantContext; -import org.broadinstitute.sting.utils.variantcontext.VariantContextUtils; +import org.broadinstitute.sting.utils.variantcontext.*; import java.io.*; import java.util.*; @@ -30,6 +32,7 @@ import java.util.*; * produces a binary ped file in individual major mode. */ @DocumentedGATKFeature( groupName = "Variant Evaluation and Manipulation Tools", extraDocs = {CommandLineGATK.class} ) +@Reference(window=@Window(start=0,stop=100)) public class VariantsToBinaryPed extends RodWalker { @ArgumentCollection protected StandardVariantContextInputArgumentCollection variantCollection = new StandardVariantContextInputArgumentCollection(); @@ -78,8 +81,6 @@ public class VariantsToBinaryPed extends RodWalker { @Argument(fullName="majorAlleleFirst",required=false,doc="Sets the major allele to be 'reference' for the bim file, rather than the ref allele") boolean majorAlleleFirst = false; - private ValidateVariants vv = new ValidateVariants(); - private static double APPROX_CM_PER_BP = 1000000.0/750000.0; private static final byte HOM_REF = 0x0; @@ -89,6 +90,8 @@ public class VariantsToBinaryPed extends RodWalker { private static final int BUFFER_SIZE = 1000; //4k genotypes per sample = Nmb for N*1000 samples + private static final String PLINK_DELETION_MARKER = "-"; + // note that HET and NO_CALL are flipped from the documentation: that's because // plink actually reads these in backwards; and we want to use a shift operator // to put these in the appropriate location @@ -101,7 +104,6 @@ public class VariantsToBinaryPed extends RodWalker { private List famOrder = new ArrayList(); public void initialize() { - initializeValidator(); writeBedHeader(); Map> sampleMetaValues = parseMetaData(); // create temporary output streams and buffers @@ -150,22 +152,25 @@ public class VariantsToBinaryPed extends RodWalker { } public Integer map(RefMetaDataTracker tracker, ReferenceContext ref, AlignmentContext context) { - if ( tracker == null || ! tracker.hasValues(variantCollection.variants) || - tracker.getFirstValue(variantCollection.variants).isFiltered() || - ! tracker.getFirstValue(variantCollection.variants).isSNP() || - ! tracker.getFirstValue(variantCollection.variants).isBiallelic()) { + if ( tracker == null ) { + return 0; + } + + VariantContext vc = tracker.getFirstValue(variantCollection.variants,context.getLocation()); + if ( vc == null || vc.isFiltered() || ! vc.isBiallelic() ) { return 0; } try { - vv.map(tracker,ref,context); - } catch (UserException e) { + validateVariantSite(vc,ref,context); + } catch (TribbleException e) { throw new UserException("Input VCF file is invalid; we cannot guarantee the resulting ped file.

This object is now allocated by the AFCalc itself, since it is heavy-weight and was badly optimized in the UG with a thread-local variable. Now, since there's already a AFCalc thread-local there, we get that optimization for free. -- Removed the interface to provide the AFCalcResultTracker to getlog10PNonRef. -- Wrote new, clean but unused AFCalcResult object that will soon replace the tracker as the external interface to the AFCalc model results, leaving the tracker as an internal tracker structure. This will allow me to (1) finally test things exhaustively, as the contracts on this class are clear (2) finalize the IndependentAllelesDiploidExactAFCalc class as it can work with a meaningfully defined result across each object --- .../ExactAFCalculationPerformanceTest.java | 16 +- .../afcalc/GeneralPloidyExactAFCalc.java | 52 +-- .../ExactAFCalculationModelUnitTest.java | 64 ++-- ...neralPloidyAFCalculationModelUnitTest.java | 6 +- .../genotyper/UnifiedGenotyperEngine.java | 15 +- .../gatk/walkers/genotyper/afcalc/AFCalc.java | 33 +- .../genotyper/afcalc/AFCalcResult.java | 321 +++++++----------- .../genotyper/afcalc/AFCalcResultTracker.java | 308 +++++++++++++++++ .../afcalc/ConstrainedDiploidExactAFCalc.java | 4 +- .../genotyper/afcalc/DiploidExactAFCalc.java | 24 +- .../IndependentAllelesDiploidExactAFCalc.java | 48 +-- .../afcalc/ReferenceDiploidExactAFCalc.java | 2 +- .../GLBasedSampleSelector.java | 8 +- 13 files changed, 560 insertions(+), 341 deletions(-) create mode 100644 public/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/AFCalcResultTracker.java diff --git a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java index 7a8a2389a..628b4f880 100644 --- a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java +++ b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java @@ -61,7 +61,7 @@ public class ExactAFCalculationPerformanceTest { final VariantContext vc = testBuilder.makeACTest(ACs, 0, nonTypePL);

Nearly all unit tests pass (expect for a contract failing one that will be dealt with in subsequent commit), due to -Infinity values from normalizeLog10. -- Changed the way that UnifiedGenotyper decides if the best model is non-ref. Previously looked at the MAP AC, but the MAP AC values are no longer provided by AFCalcResult. This is on purpose, because the MAP isn't a meaningful quantity for the exact model (i.e., everything is going to go to MLE AC in some upcoming commit). If you want to understand why come talk to me. Now uses the isPolymorphic function and the EMIT confidence, so that if pNonRef > EMIT then the site is poly, otherwise it's mono. --- .../ExactAFCalculationPerformanceTest.java | 10 +- .../ExactAFCalculationModelUnitTest.java | 123 ++++++++---------- .../genotyper/UnifiedGenotyperEngine.java | 42 +++--- .../gatk/walkers/genotyper/afcalc/AFCalc.java | 10 +- .../genotyper/afcalc/AFCalcResult.java | 20 ++- .../genotyper/afcalc/AFCalcResultTracker.java | 13 +- .../afcalc/ConstrainedDiploidExactAFCalc.java | 9 +- .../genotyper/afcalc/DiploidExactAFCalc.java | 6 +- .../IndependentAllelesDiploidExactAFCalc.java | 65 ++++----- .../GLBasedSampleSelector.java | 7 +- 10 files changed, 158 insertions(+), 147 deletions(-) diff --git a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java index 628b4f880..5f563d489 100644 --- a/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java +++ b/protected/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/ExactAFCalculationPerformanceTest.java @@ -61,7 +61,7 @@ public class ExactAFCalculationPerformanceTest { final VariantContext vc = testBuilder.makeACTest(ACs, 0, nonTypePL);

The code was badly organized, there were no unit tests, and the Diploid EXACT calculation was super slow O(n.samples ^ n.alt.alleles) -- Reorganized code into a single class AFCalc superclass that carries out the calculation and an AFCalcResult object that contains only the information we should expose to code users, and is well-validated. -- Implement a new model for the multi-allelic exact calculation that sweeps for each alt allele B all likelihoods into a bi-allelic model XB where X is all alleles != B, and calls these all separately using the reference bi-allelic model. It produces identical quals for the bi-allelic case but slightly different results for multi-allelics due to a genuine model difference in that this Independent model doesn't penalize fully all genotype configurations as occurs in the Reference multi-allelic implementation. However, it seems after much debate that the reference model is doing the wrong thing, so in fact the Independent model seems correct. This code isn't the default implementation yet, simply because I want to do some cleanup and discuss with the methods group before enabling. -- Constrained search model implemented, but will be deleted in a subsequent code cleanup -- Massive (40K) suite of unit tests the exact models, which are passing for the reference and the independent alleles exact model. -- Restored -- but isn't 100% hooked up -- the original clean bi-allelic model for Ryan to pass his optimized logless version on. -- The only way to create these AFCalc objects is through an AFCalcFactory, which again validates its arguments. The AFCalcFactory.Calculation enum exposes calculations to the UG / HC as the AFModel. -- Separated AFCalc from UG, into its own package that could in principle be pushed into utils now -- Created a simple main[] function to run performance tests of the EXACT model. --- .../sting/gatk/walkers/genotyper/afcalc/AFCalc.java | 1 + 1 file changed, 1 insertion(+) diff --git a/public/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/AFCalc.java b/public/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/AFCalc.java index 75a5bfe7b..f87084a9c 100755 --- a/public/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/AFCalc.java +++ b/public/java/src/org/broadinstitute/sting/gatk/walkers/genotyper/afcalc/AFCalc.java @@ -46,6 +46,7 @@ import java.util.List; /** * Generic interface for calculating the probability of alleles segregating given priors and genotype likelihoods + * */ public abstract class AFCalc implements Cloneable { private final static Logger defaultLogger = Logger.getLogger(AFCalc.class);
