4.1.4.0

Download release: gatk-4.1.4.0.zip
Docker image: https://hub.docker.com/r/broadinstitute/gatk/

Highlights of the 4.1.4.0 release:

  • Major improvements and fixes to Mutect2, including more intelligent handling of paired reads during genotyping and better filtering.

  • Important bug fixes to HaplotypeCaller, the joint calling pipeline, and Funcotator

  • Beta support for building/testing on Java 11 (#6119) (#6145)

    • We encourage you to try this out and give us feedback!

Full list of changes:

  • New Tools

    • AlleleFrequencyQC: a QC tool that uses VariantEval to bin variants in 1000 Genomes by allele frequency. For each bin, we compare the expected allele frequency from 1000 Genomes with the observed allele frequency in the input VCF. This was designed with arrays in mind, as a way to discover potential bugs in our pipeline. #6039)

  • Mutect2

    • Mutect2 genotyping now forces paired reads to support the same haplotype (#5831)
    • New FilterAlignmentArtifacts now realigns a locally-assembled unitig of all variant read pairs (#6143)
    • Fixed a Mutect2 bug that overfiltered by one variant (#6101)
    • Fixed a small gene panel edge case for CalculateContamination (#6137)
    • Fixed a small gene panel edge case in orientation bias filter (#6141)
    • Unified the NIO and non-NIO M2 WDLs (call-caching will now work on Terra) (#6108)
    • Updated Mutect2 pon WDL to WDL 1.0 (#6187)
    • Removed Oncotator from the M2 WDL (Funcotator is still there) (#6144)
    • Fixed an issue in the M2 WDL that could cause the Funcotate task to be ignored by tools such as dxWDL (#6077)
    • Some miscellaneous code refactoring/improvements (#6184) (#6136) (#6107) (#6159)

  • HaplotypeCaller

    • HaplotypeCaller now force-calls like Mutect2: the -genotyping-mode GENOTYPE_GIVEN_ALLELES argument is gone (now you only need to specify --alleles force-calls.vcf) and alleles are now force-called in addition to any other alleles (#6090)
    • Renamed --output-mode EMIT_ALL_SITES to --output-mode EMIT_ALL_ACTIVE_SITES, and clarified the documentation for the argument (#6181)
    • Fixed a rare bug in the genotyping engine where it could emit untrimmed alleles for SNP sites (#6044)
    • Fixed some sources of non-determinism in the HaplotypeCaller that in rare cases could cause the output to vary slightly given the same inputs (#6195) (#6104)
    • Deleted the old exact AF calculation model (#6099)

  • Joint Calling

    • Fixed a regression in GATK 4.1.3.0 that caused us to not emit the AS_QD annotation when running a joint calling pipeline with CombineGVCFs (GenomicsDB was unaffected) (#6168)
    • Fixed allele-specific annotation array length issues when alleles are subset in tools such as GenotypeGVCFs (#6079)
    • Changed AS_RankSum outputs to "." for missing values rather than "nul" (#6079)

  • Funcotator

    • Fixed a bug that caused Funcotator to outputs fields in wrong order in some cases when writing a VCF (#6178)
      • Specifically, Funcotator would output functation fields in the wrong order when there was more than 1 site in a VCF data source with the exact same position and alleles and it matched one of the variants being annotated

  • Mitochondrial pipeline

    • Renamed the output vcf with the name of the sample and supplied a default value for autosomal_median_coverage (meaning you'll now get the NuMT filter even if you don't provide the actual autosomal coverage) (#6160)

  • Miscellaneous Changes

    • Beta support for building/testing on Java 11 (#6119) (#6145)
    • UpdateVCFSequenceDictionary now supports replacing an invalid sequence dictionary in a VCF (#6140)
    • CountFalsePositives now requires an intervals file (#6120)
    • AnalyzeSaturationMutagenesis: use supplementary alignments to identify large deletions (#6092)
    • AnalyzeSaturationMutagenesis: an insert at the start codon is not in the ORF (#6121)
    • Added a check for null sequence dictionaries in the dictionary validation code (#6147)
    • Update SV Spark pipeline example shell scripts saving results to GCS (#6114)

4.1.3.0

Download release: gatk-4.1.3.0.zip
Docker image: https://hub.docker.com/r/broadinstitute/gatk/

Highlights of the 4.1.3.0 release:

  • GnarlyGenotyper, a new beta joint genotyping tool which, along with ReblockGVCF, forms part of a forthcoming more scalable version of our joint genotyping pipeline that we call the "GATK Biggest Practices" pipeline
  • FuncotateSegments, a new beta companion tool to Funcotator that performs functional annotation on a segment file (.seg) rather than a VCF
  • GenomicsDBImport now has the ability to incrementally update an existing GenomicsDB workspace
  • Several important bug fixes to HaplotypeCaller and Mutect2

Compatibility notes:

  • GermlineCNVCaller models built in cohort mode with previous releases are no longer compatible. Users should rebuild these models with this release before running GermlineCNVCaller in case mode. See the CNV Tools section below for more details.

Full list of changes:

  • New Tools

    • GnarlyGenotyper (beta tool) (#4947) (#6075)

      • The GnarlyGenotyper is designed to perform joint genotyping on cohorts of at least tens of thousands of samples called with HaplotypeCaller and post-processed with ReblockGVCF to produce a multi-sample callset in a super highly scalable manner.
      • Caveats:
        • GnarlyGenotyper is intended to be used with GVCFs for which low quality variants have already been removed, derived from post-processing HaplotypeCaller GVCFs with ReblockGVCF. See the "Biggest Practices" usage example in the ReblockGVCF docs for details.
        • GnarlyGenotyper does not subset alternate alleles and can return some highly multi-allelic sites. PLs will not be output for sites with more than 6 alts to save space.
        • GnarlyGenotyper assumes all diploid genotypes
      • Annotations:
        • To generate all the annotations necessary for VQSR, input variants to the GnarlyGenotyper must include the QUALapprox and VarDP annotations along with the latest RAW_MQandDP annotation.
        • If allele-specific annotations are present, they will be used appropriately and a new AS_AltDP annotation giving the total depth across samples for each alternate allele will be added.
      • A GATK "Biggest Practices" pipeline including the GnarlyGenotyper is forthcoming pending some fixes improving on the above caveats.

    • FuncotateSegments (beta tool) (#5941)

      • A companion tool to Funcotator that performs functional annotation on a segment file (.seg) rather than a VCF
      • The Somatic CNV pipeline can optionally run this tool for functional annotation

  • HaplotypeCaller/Mutect2

    • Fixed a regression in HaplotypeCaller/Mutect2 that caused some variants to be lost at sites with high complexity (#5952)
    • Fixed a GGA (GENOTYPE_GIVEN_ALLELES) mode bug in HaplotypeCaller/Mutect2 where added alleles' cigars could have soft clips (#6047)
      • This bug would manifest as a "Cigar cannot be null" error
    • Fixed a bug where cached indel informativeness values could be incorrectly applied to the wrong sites in HaplotypeCaller/Mutect2 (#5911)
    • Fixed an edge case in HaplotypeCaller/Mutect2 where dangling end merging creates cycles (#5960)
    • Added hidden arguments to the assembly engine to track found haplotype counts and kmers used (#6049)
    • Fixed a bug in CalculateContamination when contamination is indistinguishable from zero (#5971)
    • Fixed a bug where normal p value argument in FilterMutectCalls was declared static (#5982)

  • CNV Tools

    • Added FuncotateSegments as an option to the Somatic CNV WDL (#5967)
    • Added QC metrics to the Germline CNV workflow (#6017)
    • Enabled GC-bias correction by default in CNV workflows (#5966)
    • Added denoised coverage file concatenation output to gCNV postprocessor (#5823) Note: The addition of this feature breaks compatibility with gCNV cohort-mode models built with previous releases.
    • Changed cr.igv.seg output of ModelSegments to give log2 Segment_Mean. (#5976)
    • Fixed CNV plotting script to allow spaces in input filenames. (#5983)

  • GenomicsDBImport

    • Added support for making incremental updates to existing workspaces (#5970)
      • This can be done using the new --genomicsdb-update-workspace-path argument
    • Fixed a crash in GenomicsDBImport on queries at positions inside deletions (#5899)
    • Treat AS_QUALapprox and AS_VarDP strings as array of int vectors (#5933)

  • Mitochondrial Calling Pipeline

    • Added NIO support and updated to WDL 1.0 (#6074)

  • Spark Tools

    • Removed the beta label from many simple Spark tools (#5991)
    • Bug fix for reading references from GCS on Spark (#6070)
    • Eliminated an unnecessary sort step in HaplotypeCallerSpark (#5909)
    • Fixed BaseRecalibratorSpark failure on a cluster due to system classloader issue (#5979)
    • Added a WDL for ReadsPipelineSpark (#5904)
    • Added a command-line argument to toggle using NIO on reading for Spark (#6010)
    • Added advanced arguments to MarkDuplicatesSpark to allow non-queryname sorted inputs when specifying multiple input bams and to treat unsorted inputs as queryGroup-sorted (#5974)
    • Clarified the behavior of MarkDuplicatesSpark when given multiple input bams, and improved the sorting behavior if given a mix of queryname-sorted and query-grouped bams (#5901)
    • Changed spark.yarn.executor.memoryOverhead to spark.executor.memoryOverhead as promoted by Spark 2.3 (#6032)
    • Handle newly-added arguments in ApplyBQSRUniqueArgumentCollection (#5949)

  • Miscellaneous Changes

    • Added a new BaseQualityHistogram variant annotation to generate base quality histograms (#5986)
    • Added a new SoftClippedReadFilter that can filter out reads where the ratio of soft-clipped bases to total bases exceeds some given value (#5995)
    • Fixed a serious bug in ValidateVariants where the tool would silently do no validation in the default case when a DBSNP file was not provided (#5984)
    • Fixed a "Record covers a position previously traversed" error in ValidateVariants for GVCFS with multiple contigs (#6028)
    • The RMSMappingQuality annotation now requires the --allow-old-rms-mapping-quality-annotation-data argument to run with GVCFs created by older versions of the GATK (#6060)
    • Added a simple TSV/CSV/XSV writer with cloud write support as an alternative to TableWriter (#5930)
    • Funcotator: added Funcotator stand-alone WDL to supported area (#5999)
    • Extracted the GenotypeGVCFs engine into publicly accessible class/function (#6004)
    • Refactored VariantEval methods to allow subclasses to override (#5998)
    • AnalyzeSaturationMutagenesis: arbitrarily choose 1 read for disjoint pairs, dump rejected reads, and various other improvements (#5926) (#6043)
    • Normalized some AssemblyRegion args in HaplotypeCallerSpark (#5977)
    • Don't redundantly delete temporary directories in RSCriptExecutor (#5894)

4.1.2.0

Download release: gatk-4.1.2.0.zip
Docker image: https://hub.docker.com/r/broadinstitute/gatk/

Highlights of the 4.1.2.0 release:

  • Two new tools, MethylationTypeCaller and AnalyzeSaturationMutagenesis (see below for descriptions)
  • Significant improvements to GENOTYPE_GIVEN_ALLELES mode in Mutect2 and HaplotypeCaller
  • Fixed a serious bug in Funcotator that could cause END positions to be wrong for some deletions in MAF output
  • Significant updates to the mitochondrial calling pipeline

Full list of changes:

  • New Tools

    • MethylationTypeCaller (#5762)
      • Identifies methylated bases from bisulfite sequencing data. Given a bisulfite sequenced, methylation-aware aligned BAM and a reference, it outputs methylation-site coverage to a specified output vcf file.
    • AnalyzeSaturationMutagenesis (#5803)(#5883)
      • Processes reads from a saturation mutagenesis experiment, an experiment that systematically perturbs a mini-gene to ascertain which amino-acid variations are tolerable at each codon of the open reading frame. Its main job is to discover variations from wild-type sequence among the reads, and to summarize the variations observed.

  • Mutect2

    • Made significant improvements to GENOTYPE_GIVEN_ALLELES mode in Mutect2 and HaplotypeCaller (#5874). These improvements are described in more detail in #5857
    • CalculateContamination now works much better for very small gene panels (#5873)
    • We now correctly handle inputs with 100% contamination in Mutect2 filtering (#5853)
    • Mutect2 now uses natural logarithms internally (#5858). This does not change any outputs.
    • Minor update to the Mutect2 PON WDL (#5859)

  • Funcotator

    • Fixed a serious bug that could cause END positions to be wrong for some deletions in MAF output (#5876)
    • The tool now throws a user error for an AD field with only 1 value in MAF mode (#5860)
    • Added a new filter to FilterFuncotations. For two autosomal recessive genes, MUTYH and ATP7B, homozygous variants and compound heterozygous variants will be tagged and added to the output vcf. (#5843)

  • Mitochondrial Calling Pipeline

    • Updated the pipeline for the new Mutect2 filtering scheme and pulled filtering after the liftover and recombining of the VCF. (#5847)
    • Made the subsetting of the WGS bam fast by using PrintReads over just chrM instead of traversing the whole bam for NuMT mates. (#5847)
    • Moved polymorphic NuMTs based on autosomal coverage to a filter (it was an annotation before) (#5847)
    • Added an option to hard filter by VAF (#5847)
    • Bug fix for large input files to the mitochondrial pipeline (we now include the size of the input BAM/CRAM when calculating disk size, when necessary) (#5861)

  • Structural Variation Calling Pipeline

    • Bug fix to QNameFinder to handle reads with negative unclipped starts (#5864)

  • Miscellaneous Changes

    • Added a --min-fragment-length argument to the FragmentLengthReadFilter (#5886)
    • Added a --spark-verbosity argument to control verbosity of Spark-generated logs (#5825)
    • Added a new WalkerBase abstract class to be used for all built-in walkers (#4964)
    • Exposed transient attributes in the GATKRead API (#5664)
    • Convert more code to use GATKPathSpecifier (#5870) (#5832). This also fixes an InvalidPathException on Windows machines.
    • Fixes to the test suite related to the recent introduction of a codec for Picard interval lists (#5879)
    • Eliminated an error message during the Docker build in Travis logs by creating a directory before copying to it. (#5878)

  • Documentation

    • Updated the Mutect2 WDL README with Funcotator information (#5892)
    • Updated a usage example for CreateHadoopBamSplittingIndex (#5898)

  • A tensorflow update for CNNScoreVariants that speeds up the tool by roughly ~2X when using the 2D model.
  • Important updates to the mitochondrial calling pipeline, and improved memory usage in the CNV pipeline.
  • Important bug fixes to Funcotator, VariantEval, GenomicsDBImport, and other tools, as well as to the --pedigree argument for annotations.

Docker image: https://hub.docker.com/r/broadinstitute/gatk/

Full list of changes:

  • HaplotypeCaller

    • Greatly improved the performance of the ReferenceConfidenceModel using dynamic programming and caching (#5607)
      • This speeds up whole-genome GVCF mode calling (-ERC GVCF) by ~33% in our tests!

    • Fixed rare infinite recursion bug in KBestHaplotypeFinder (also affects Mutect2)(#5786)

  • Mutect2

    • Overhaul of FilterMutectCalls, which now applies a single threshold to an overall error probability (#5688)
      • FilterMutectCalls automatically determines the optimal threshold.
      • The new somatic clustering model learns tumors' allele fraction spectra and overall SNV and indel mutation rates in order to improve filtering.
      • Includes a rewrite of Mutect2 documentation -- better organization and now includes command line examples in addition to math.

4.1.0.0

It's been a year since the GATK 4.0.0.0 release in January 2018, and we decided that it was time to package up the past year's worth of GATK improvements into a new major release, which we're calling version 4.1.0.0!

To commemorate this milestone, we'll be publishing a series of in-depth technical articles and blog posts covering the major new features in version 4.1.0.0 on the official GATK blog.

Below we've compiled the highlights of the new features added between versions 4.0.0.0 and 4.1.0.0. If you're interested in seeing only the changes between the last release (4.0.12.0) and this release (4.1.0.0), click here instead.

Official docker image is here: https://hub.docker.com/r/broadinstitute/gatk/

Major changes between versions 4.0.0.0 and 4.1.0.0 (January 2018 to January 2019):

  • Next-Gen VQSR Replacement For Single-Sample

    • CNNScoreVariants is now out of beta and ready for production use
    • Performs variant training and scoring using a convolutional neural network.
    • Single-sample only
    • Produces better results than the legacy VariantRecalibrator (VQSR) and comparable or better results to third-party tools like DeepVariant
    • Sophisticated 2D model that uses the reads

  • Major HaplotypeCaller Improvements

    • Now genotypes and outputs spanning deletions
    • Now outputs VCF spec-compliant phased variants
    • Can emit MNPs via a new --max-mnp-distance argument
    • Important fix to the reference confidence calculation upstream of indels
    • New HaplotypeCaller priors for variants sites and homRef blocks
      • Added new --population-callset argument allowing an external panel of variants to be specified to inform the frequency distribution underlying the genotype priors
      • Added new --num-reference-samples-if-no-call argument to control whether to infer (and with what effective strength) that only reference alleles were observed at sites not seen in any panel

  • Major Mutect2 Improvements

    • Mutect2 is now out of beta
    • Support for multi-sample calling
    • Lots of support for high-depth calling such as cfDNA, UMIs, mitochondria, including a new active region likelihood, probabilistic assembly graph pruning that adjusts to the local depth, a new mitochondria mode, and new filters for blood biopsy and mitochondria

    • Significant speed improvements
    • Improved allele fraction estimation
    • Initial GVCF output support

  • New allele frequency / qual score model

    • Is now the default in HaplotypeCaller and GenotypeGVCFs
    • Optimized for greater speed, should resolve many GenotypeGVCFs memory issues
    • Rare numerical finite precision issues in the allele-specific qual have been resolved

  • Major Improvements to the CNV (Copy Number Variation) tools

    • Regions of excessive sequencing depth are excluded from evidence collection and assembly, improving runtime performance.
    • A major overhaul of our algorithm for calling events based on local assemblies improves accuracy and allows for the accurate reporting of small complex SVs.
    • A machine learning (xgBoost) based classifier for SV evidence improves runtime and increases accuracy by determining which regions should be fed into the local assembly workflow.

  • Spark Improvements

4.0.10.1

This is a small release that improves the calculation of the MQ (mapping quality) annotation, which provides an estimate of the overall mapping quality of reads supporting a variant call. It also introduces a number of experimental improvements to the CNV workflows, as well as a bug fix to LocusWalkerSpark.

As usual, a docker image for this release can be downloaded from https://hub.docker.com/r/broadinstitute/gatk/

Full list of changes in this release:

  • Improve MQ calculation accuracy (#4969)

    • Change raw MQ to a tuple of (sumSquaredMQs, totalDepth) for better accuracy where there are lots of uninformative reads or called single-sample variants with homRef genotypes.
    • Note that incorporating this change into a pipeline will require a concomitant update to this version for GenomicsDBImport and GenotypeGVCFs.

  • Updated SimpleGermlineTagger and somatic CNV experimental post-processing workflow with several experimental changes that improve precision results, and expand possible evaluations, of GATK CNV (#5252)

    • New script combine_tracks.wdl for post-processing somatic CNV calls. This wdl will perform two operations:
      • Increases precision by removing:
        • germline segments. As a result, the WDL requires the matched normal segments.
        • Areas of common germline activity or error from other cancer studies.
      • Converts the tumor model seg file to the same format as AllelicCapSeg, which can be read by ABSOLUTE. This is currently done inline in the WDL.
        • This is not a trivial conversion, since each segment must be called whether it is balanced or not (MAF =? 0.5). The current algorithm relies on hard filtering and may need updating pending evaluation.
        • For more information about AllelicCapSeg and ABSOLUTE, see:

      • SimpleGermlineTagger now uses reciprocal overlap to in addition to breakpoint matching when determining a possible germline event. This greatly improved results in areas near centromeres.
      • Added tool MergeAnnotatedRegionsByAnnotation. This simple tool will merge genomic regions (specified in a tsv) when given annotations (columns) contain exact values in neighboring segments and the segments are within a specified maximum genomic distance.
    • New scripts multi_combine_tracks.wdl and aggregate_combine_tracks.wdl which run combine_tracks.wdl on multiple pairs and combine the results into one seg file for easy consumption by IGV.

  • LocusWalkerSpark: fix issue where intervals with no reads were being dropped (#5222)

    • This fixes the bug reported in #3823

  • Added SparkTestUtils.roundTripThroughJavaSerialization() method for better serialization testing on Spark (#5257)

  • Build system: set the same compiler flags for all gradle JavaCompile tasks (#5256)

Highlights of this release include a new tool ReblockGVCF, a bug fix for a crash in Mutect2, and a more efficient distribution mechanism for the reference and VCFs in Spark tools.

As usual, a docker image for this release can be downloaded from https://hub.docker.com/r/broadinstitute/gatk/

Full list of changes in this release:

  • Added a new experimental tool ReblockGVCF (#4940)

    • A tool to merge reference blocks in single-sample GVCFs for smaller filesizes

  • Mutect2:

    • Fixed a bug in the PalindromeArtifactClipReadTransformer (#5241)
      • This filter would crash with an out-of-bounds error for fragment lengths and/or mate start positions that went off the end of a contig.
    • Changed the way the log10AlleleFractions are calculated in SomaticLikelihoodsEngine: now we use the mean of the posterior of the allele fractions. (#5231)
    • Reword comments in Mutect2 WDL to not refer to the old orientation bias filter as deprecated. (#5196)
    • Cited CGA in Mutect docs (#5228)

  • HaplotypeCaller: Allow MNP calling in GVCF mode with stern warnings about not trying joint-genotyping from the resulting GVCFs. (#5182)

    • HaplotypeCaller will now allow you to output MNPs in GVCF mode with a warning, however since joint genotyping of MNPs is unsupported, CombineGVCFs and GenomicsDBImport will now refuse to process GVCFs containing MNPs.

  • GATK Spark tools:

    • Migrated most Spark tools that take a reference and/or VCF to use Spark's intrinsic file copying mechanism instead of broadcast to distribute the reference and VCFs to worker nodes (#5127) (#5221)
      • This improves the performance of Spark tools that take a reference and/or VCF as side inputs, as the new distribution mechanism doesn't load the entire contents of the files into memory like broadcast did.
      • As a side effect of this change, support for 2bit references has been removed from tools that were migrated to the new distribution mechanism (in particular, BaseRecalibratorSpark and HaplotypeCallerSpark).
      • The CNV Spark tools have not yet been migrated, and still support 2bit references for now.
    • Bug fix: ensure that intervals with no reads are not dropped by the SparkSharder (#5248)

  • Funcotator:

    • Added command line exclusion lists, so that users can prune fields from the output. (#5226)
    • Added Funcotator excluded fields option explicitly to the M2 WDLs. (#5242)

  • Fix a multithreaded race condition in GenotypeLikelihoodCalculators by synchronizing updates of shared genotype likelihood tables. (#5071)

    • This bug affected HaplotypeCallerSpark, but not the regular HaplotypeCaller

  • GenomicsDB: added in machinery to allow per-annotation combine operations to be specified (#4993)

  • GATK Engine: Hooked up CountingVariantFilter to VariantWalkers (#4954)

  • StreamingPythonScriptExecutor: added a new message to the StreamingProcessController ack FIFO protocol to allow additional message detail to be passed as part of a negative ack. (#5170)

    • This improves exception message propagation for fatal errors when running Python tools.

  • gCNV WDLs:

    • Tar calls from all samples. (#5225)
      • This fixes an issue where the gCNV WGS cohort germline WDL was outputting vcf files with names that do not correspond to the actual samples inside the files.
    • Added multi-sample functionality to gCNV case mode WDL, and added a wrapper for gCNV case mode WDL to help optimize cloud computation cost. Also optimized how data is sent to postprocessing task in gCNV WDLs. (#5176)

  • gCNV kernel: Enforced ViterbiSegmentationEngine to analyze single samples only (#5176)

  • Added a dataproc-cluster-ui script to easily open the Spark UI on dataproc clusters (#5188)

  • Fixed pom issues that prevented publishing to maven central (#5224)

  • Added tabix to the docker base image (#5247)
