As featured in this forum question.

Two main things account for these kinds of differences, both linked to default behaviors of the tools:

  • The tools downsample to different depths of coverage

  • The tools apply different read filters

In both cases, you can end up looking at different sets or numbers of reads, which causes some of the annotation values to be different. It's usually not a cause for alarm. Remember that many of these annotations should be interpreted relatively, not absolutely.

IMPORTANT NOTE: This document is out of date and will be replaced soon. In the meantime, you can find accurate information on how to run SnpEff in a compatible way with GATK in the SnpEff documentation, and instructions on what steps are necessary in the presentation on Functional Annotation linked in the comments below.

Our testing has shown that not all combinations of snpEff/database versions produce high-quality results. Be sure to read this document completely to familiarize yourself with our recommended best practices BEFORE running snpEff.


Until recently we were using an in-house annotation tool for genomic annotation, but the burden of keeping the database current and our lack of ability to annotate indels has led us to employ the use of a third-party tool instead. After reviewing many external tools (including annoVar, VAT, and Oncotator), we decided that SnpEff best meets our needs as it accepts VCF files as input, can annotate a full exome callset (including indels) in seconds, and provides continually-updated transcript databases. We have implemented support in the GATK for parsing the output from the SnpEff tool and annotating VCFs with the information provided in it.

SnpEff Setup and Usage

Download the SnpEff core program. If you want to be able to run VariantAnnotator on the SnpEff output, you'll need to download a version of SnpEff that VariantAnnotator supports from this page (currently supported versions are listed below). If you just want the most recent version of SnpEff and don't plan to run VariantAnnotator on its output, you can get it from here.

After unzipping the core program, open the file snpEff.config in a text editor, and change the "database_repository" line to the following:

database_repository = http://sourceforge.net/projects/snpeff/files/databases/

Then, download one or more databases using SnpEff's built-in download command:

java -jar snpEff.jar download GRCh37.64

You can find a list of available databases here. The human genome databases have GRCh or hg in their names. You can also download the databases directly from the SnpEff website, if you prefer.

The download command by default puts the databases into a subdirectory called data within the directory containing the SnpEff jar file. If you want the databases in a different directory, you'll need to edit the data_dir entry in the file snpEff.config to point to the correct directory.

Run SnpEff on the file containing your variants, and redirect its output to a file. SnpEff supports many input file formats including VCF 4.1, BED, and SAM pileup. Full details and command-line options can be found on the SnpEff home page.

Supported SnpEff Versions

If you want to take advantage of SnpEff integration in the GATK, you'll need to run SnpEff version **2.0.5*. Note: newer versions are currently unsupported by the GATK, as we haven't yet had the reources to test it.

Current Recommended Best Practices When Running SnpEff

These best practices are based on our analysis of various snpEff/database versions as described in detail in the Analysis of SnpEff Annotations Across Versions section below.

  • We recommend using only the GRCh37.64 database with SnpEff 2.0.5. The more recent GRCh37.65 database produces many false-positive Missense annotations due to a regression in the ENSEMBL Release 65 GTF file used to build the database. This regression has been acknowledged by ENSEMBL and is supposedly fixed as of 1-30-2012; however as we have not yet tested the fixed version of the database we continue to recommend using only GRCh37.64 for now.

  • We recommend always running with -onlyCoding true with human databases (eg., the GRCh37.* databases). Setting -onlyCoding false causes snpEff to report all transcripts as if they were coding (even if they're not), which can lead to nonsensical results. The -onlyCoding false option should only be used with databases that lack protein coding information.

  • Do not trust annotations from versions of snpEff prior to 2.0.4. Older versions of snpEff (such as 2.0.2) produced many incorrect annotations due to the presence of a certain number of nonsensical transcripts in the underlying ENSEMBL databases. Newer versions of snpEff filter out such transcripts.

Analyses of SnpEff Annotations Across Versions

See our analysis of the SNP annotations produced by snpEff across various snpEff/database versions here.

  • Both snpEff 2.0.2 + GRCh37.63 and snpEff 2.0.5 + GRCh37.65 produce an abnormally high Missense:Silent ratio, with elevated levels of Missense mutations across the entire spectrum of allele counts. They also have a relatively low (~70%) level of concordance with the 1000G Gencode annotations when it comes to Silent mutations. This suggests that these combinations of snpEff/database versions incorrectly annotate many Silent mutations as Missense.

  • snpEff 2.0.4 RC3 + GRCh37.64 and snpEff 2.0.5 + GRCh37.64 produce a Missense:Silent ratio in line with expectations, and have a very high (~97%-99%) level of concordance with the 1000G Gencode annotations across all categories.

See our comparison of SNP annotations produced using the GRCh37.64 and GRCh37.65 databases with snpEff 2.0.5 here

  • The GRCh37.64 database gives good results on the condition that you run snpEff with the -onlyCoding true option. The -onlyCoding false option causes snpEff to mark all transcripts as coding, and so produces many false-positive Missense annotations.

  • The GRCh37.65 database gives results that are as poor as those you get with the -onlyCoding false option on the GRCh37.64 database. This is due to a regression in the ENSEMBL release 65 GTF file used to build snpEff's GRCh37.65 database. The regression has been acknowledged by ENSEMBL and is due to be fixed shortly.

See our analysis of the INDEL annotations produced by snpEff across snpEff/database versions here

  • snpEff's indel annotations are highly concordant with those of a high-quality set of genomic annotations from the 1000 Genomes project. This is true across all snpEff/database versions tested.

Example SnpEff Usage with a VCF Input File

Below is an example of how to run SnpEff version 2.0.5 with a VCF input file and have it write its output in VCF format as well. Notice that you need to explicitly specify the database you want to use (in this case, GRCh37.64). This database must be present in a directory of the same name within the data_dir as defined in snpEff.config.

java -Xmx4G -jar snpEff.jar eff -v -onlyCoding true -i vcf -o vcf GRCh37.64 1000G.exomes.vcf > snpEff_output.vcf

In this mode, SnpEff aggregates all effects associated with each variant record together into a single INFO field annotation with the key EFF. The general format is:

EFF=Effect1(Information about Effect1),Effect2(Information about Effect2),etc.

And here is the precise layout with all the subfields:


It's also possible to get SnpEff to output in a (non-VCF) text format with one Effect per line. See the SnpEff home page for full details.

Adding SnpEff Annotations using VariantAnnotator

Once you have a SnpEff output VCF file, you can use the VariantAnnotator walker to add SnpEff annotations based on that output to the input file you ran SnpEff on.

There are two different options for doing this:

Option 1: Annotate with only the highest-impact effect for each variant

NOTE: This option works only with supported SnpEff versions as explained above. VariantAnnotator run as described below will refuse to parse SnpEff output files produced by other versions of the tool, or which lack a SnpEff version number in their header.

The default behavior when you run VariantAnnotator on a SnpEff output file is to parse the complete set of effects resulting from the current variant, select the most biologically-significant effect, and add annotations for just that effect to the INFO field of the VCF record for the current variant. This is the mode we plan to use in our Production Data-Processing Pipeline.

When selecting the most biologically-significant effect associated with the current variant, VariantAnnotator does the following:

  • Prioritizes the effects according to the categories (in order of decreasing precedence) "High-Impact", "Moderate-Impact", "Low-Impact", and "Modifier", and always selects one of the effects from the highest-priority category. For example, if there are three moderate-impact effects and two high-impact effects resulting from the current variant, the annotator will choose one of the high-impact effects and add annotations based on it. See below for a full list of the effects arranged by category.

  • Within each category, ties are broken using the functional class of each effect (in order of precedence: NONSENSE, MISSENSE, SILENT, or NONE). For example, if there is both a NON_SYNONYMOUS_CODING (MODERATE-impact, MISSENSE) and a CODON_CHANGE (MODERATE-impact, NONE) effect associated with the current variant, the annotator will select the NON_SYNONYMOUS_CODING effect. This is to allow for more accurate counts of the total number of sites with NONSENSE/MISSENSE/SILENT mutations. See below for a description of the functional classes SnpEff associates with the various effects.

  • Effects that are within a non-coding region are always considered lower-impact than effects that are within a coding region.

Example Usage:

java -jar dist/GenomeAnalysisTK.jar \
     -T VariantAnnotator \
     -R /humgen/1kg/reference/human_g1k_v37.fasta \
     -A SnpEff \       
     --variant 1000G.exomes.vcf \        (file to annotate)
     --snpEffFile snpEff_output.vcf \    (SnpEff VCF output file generated by running SnpEff on the file to annotate)
     -L 1000G.exomes.vcf \
     -o out.vcf

VariantAnnotator adds some or all of the following INFO field annotations to each variant record:

  • SNPEFF_EFFECT - The highest-impact effect resulting from the current variant (or one of the highest-impact effects, if there is a tie)
  • SNPEFF_IMPACT - Impact of the highest-impact effect resulting from the current variant (HIGH, MODERATE, LOW, or MODIFIER)
  • SNPEFF_FUNCTIONAL_CLASS - Functional class of the highest-impact effect resulting from the current variant (NONE, SILENT, MISSENSE, or NONSENSE)
  • SNPEFF_CODON_CHANGE - Old/New codon for the highest-impact effect resulting from the current variant
  • SNPEFF_AMINO_ACID_CHANGE - Old/New amino acid for the highest-impact effect resulting from the current variant
  • SNPEFF_GENE_NAME - Gene name for the highest-impact effect resulting from the current variant
  • SNPEFF_GENE_BIOTYPE - Gene biotype for the highest-impact effect resulting from the current variant
  • SNPEFF_TRANSCRIPT_ID - Transcript ID for the highest-impact effect resulting from the current variant
  • SNPEFF_EXON_ID - Exon ID for the highest-impact effect resulting from the current variant

Example VCF records annotated using SnpEff and VariantAnnotator:

1   874779  .   C   T   279.94  . AC=1;AF=0.0032;AN=310;BaseQRankSum=-1.800;DP=3371;Dels=0.00;FS=0.000;HRun=0;HaplotypeScore=1.4493;InbreedingCoeff=-0.0045;

1   874816  .   C   CT  2527.52 .   AC=15;AF=0.0484;AN=310;BaseQRankSum=-11.876;DP=4718;FS=48.575;HRun=1;HaplotypeScore=91.9147;InbreedingCoeff=-0.0520;

Option 2: Annotate with all effects for each variant

VariantAnnotator also has the ability to take the EFF field from the SnpEff VCF output file containing all the effects aggregated together and copy it verbatim into the VCF to annotate.

Here's an example of how to do this:

java -jar dist/GenomeAnalysisTK.jar \
     -T VariantAnnotator \
     -R /humgen/1kg/reference/human_g1k_v37.fasta \      
     -E resource.EFF \
     --variant 1000G.exomes.vcf \      (file to annotate)
     --resource snpEff_output.vcf \    (SnpEff VCF output file generated by running SnpEff on the file to annotate)
     -L 1000G.exomes.vcf \
     -o out.vcf

Of course, in this case you can also use the VCF output by SnpEff directly, but if you are using VariantAnnotator for other purposes anyway the above might be useful.

List of Genomic Effects

Below are the possible genomic effects recognized by SnpEff, grouped by biological impact. Full descriptions of each effect are available on this page.

High-Impact Effects


Moderate-Impact Effects

  • CODON_CHANGE (note: this effect is used by SnpEff only for MNPs, not SNPs)

Low-Impact Effects



  • NONE
  • CDS
  • GENE
  • EXON

Functional Classes

SnpEff assigns a functional class to certain effects, in addition to an impact:

  • NONSENSE: assigned to point mutations that result in the creation of a new stop codon
  • MISSENSE: assigned to point mutations that result in an amino acid change, but not a new stop codon
  • SILENT: assigned to point mutations that result in a codon change, but not an amino acid change or new stop codon
  • NONE: assigned to all effects that don't fall into any of the above categories (including all events larger than a point mutation)

The GATK prioritizes effects with functional classes over effects of equal impact that lack a functional class when selecting the most significant effect in VariantAnnotator. This is to enable accurate counts of NONSENSE/MISSENSE/SILENT sites.

GATK 3.2 was released on July 14, 2014. Itemized changes are listed below. For more details, see the user-friendly version highlights.

We also want to take this opportunity to thank super-user Phillip Dexheimer for all of his excellent contributions to the codebase, especially for this release.

Haplotype Caller

  • Various improvements were made to the assembly engine and likelihood calculation, which leads to more accurate genotype likelihoods (and hence better genotypes).
  • Reads are now realigned to the most likely haplotype before being used by the annotations, so AD and DP will now correspond directly to the reads that were used to generate the likelihoods.
  • The caller is now more conservative in low complexity regions, which significantly reduces false positive indels at the expense of a little sensitivity; mostly relevant for whole genome calling.
  • Small performance optimizations to the function to calculate the log of exponentials and to the Smith-Waterman code (thanks to Nigel Delaney).
  • Fixed small bug where indel discovery was inconsistent based on the active-region size.
  • Removed scary warning messages for "VectorPairHMM".
  • Made VECTOR_LOGLESS_CACHING the default implementation for PairHMM.
  • When we subset PLs because alleles are removed during genotyping we now also subset the AD.
  • Fixed bug where reference sample depth was dropped in the DP annotation.

Variant Recalibrator

  • The -mode argument is now required.
  • The plotting script now uses the theme instead of opt functions to work with recent versions of the ggplot2 R library.


  • The plotting script now uses the theme instead of opt functions to work with recent versions of the ggplot2 R library.

Variant Annotator

  • SB tables are created even if the ref or alt columns have no counts (used in the FS and SOR annotations).

Genotype GVCFs

  • Added missing arguments so that now it models more closely what's available in the Haplotype Caller.
  • Fixed recurring error about missing PLs.
  • No longer pulls the headers from all input rods including dbSNP, rather just from the input variants.
  • --includeNonVariantSites should now be working.

Select Variants

  • The dreaded "Invalid JEXL expression detected" error is now a kinder user error.

Indel Realigner

  • Now throws a user error when it encounters reads with I operators greater than the number of read bases.
  • Fixed bug where reads that are all insertions (e.g. 50I) were causing it to fail.


  • Now computes posterior probabilities only for SNP sites with SNP priors (other sites have flat priors applied).
  • Now computes genotype posteriors using likelihoods from all members of the trio.
  • Added annotations for calling potential de novo mutations.
  • Now uses PP tag instead of GP tag because posteriors are Phred-scaled.

Cat Variants

  • Can now process .list files with -V.
  • Can now handle BCF and Block-Compressed VCF files.

Validate Variants

  • Now works with gVCF files.
  • By default, all strict validations are performed; use --validationTypeToExclude to exclude specific tests.


  • Now use '--use_IUPAC_sample sample_name' to specify which sample's genotypes should be used for the IUPAC encoding with multi-sample VCF files.


  • Refactored maven directories and java packages replacing "sting" with "gatk".
  • Extended on-the-fly sample renaming feature to VCFs with the --sample_rename_mapping_file argument.
  • Added a new read transformer that refactors NDN cigar elements to one N element.
  • Now a Tabix index is created for block-compressed output formats.
  • Switched outputRoot in SplitSamFile to an empty string instead of null (thanks to Carlos Barroto).
  • Enabled the AB annotation in the reference model pipeline (thanks to John Wallace).
  • We now check that output files are specified in a writeable location.
  • We now allow blank lines in a (non-BAM) list file.
  • Added legibility improvements to the Progress Meter.
  • Allow for non-tab whitespace in sample names when performing on-the-fly sample-renaming (thanks to Mike McCowan).
  • Made IntervalSharder respect the IntervalMergingRule specified on the command line.
  • Sam, tribble, and variant jars updated to version 1.109.1722; htsjdk updated to version 1.112.1452.

Comments (5)

I am struggling with adding AlleleBalanceBySample and StrandBiasBySample to my joint VCF file. The data through joint VCF were generated with GATK 3.2-2, and I have tried using the VariantAnnotator as well as repeating the GenotypeGVCF step specifying the annotations. I have also tried using the GenotypeGVCFs tool from 3.3-0, but am trying to avoid running the HC again in the interest of time. For the strand bias by sample I can see why the VariantAnnotator approach would fail, as the information is not contained in the joint VCF file, but it is there in the GVCF. For the allele balance by sample it seems the info is already in the joint VCF, so either VariantAnnotation or rerunning GenotypeGVCFs seem like they should work.

I should add that when I do try to add these annotations using GenotypeGVCFs, they are noted in the header ##FORMAT section, but not in the actual F:O:R:M:A:T.

Any clues or hints (or admonitions!) much appreciated.

Hello GATK Team,

I am following a workflow that assumes the user is working with GATK 2.2-16. I am, however, using the current GATK version. Curious, is -V:variant,VCF vcfFile still a valid way to call a command when using VariantAnnotator on the latest GATK release?

Comments (3)


In the best practices for vqsr in indel mode it is recommended to use the annotation SOR. However, when I try to add this annotation using VariantAnnotator it only adds it to the SNP calls not the indel calls. Does this mean SOR should not be used for vqsr in indel mode?

I'm using VariantAnnotator to add annotations to variants from a bunch of sources. One issue that I have is that for some variants, there are multiple annotations in a supplied resource. In the docs, I read

"Note that if there are multiple records in the resource file that overlap the given position, one is chosen randomly."

Can this behaviour be altered? I need to output all annotations for a record, either on a single line, or on multiple.

In the case i'm working on, one line has the annotation "CLNSIG=5" (i.e. a known pathogenic variant) and the other (likely older record) is "CLNSIG=1" i.e. a variant of unknown significance. I need to output both so I can filter downstream (using SelectVariants) to select those where "CLNSIG=5".

I have a vcf that I want to annotate the info DP field matching on the rs IDs. According to the documentation this should be able to be done via the VariantAnnotator and using the -A for the field I want.

 java -jar GenomeAnalysisTK.jar \ 
 -T  VariantAnnotator \
 -R ref.fasta \
 --variant input.vcf \ 
 -L input.vcf \
 -o output.vcf \
 --dbsnp dbSnp.vcf \
 -A DepthOfCoverage

It is running and annotating the INFO field with the DB annotation with no value. Why is the DP annotation not being annotated? Thanks!

Comments (4)


I used the variant annotator on a multi sample vcf and I am happy to report that it worked great (especially being tree reducible). I had a question that I could not find in the documentation. For each variant call it the annotator would either declare a sample to be a "hiConfDeNovo" or a "loConfDeNovo" or there would be no assessment whatsover (indicating I suspect no De Novos for that variant call).

My question: What defines a "hiConfDeNovo" and what defines a "loConfDeNovo" as it is used by the annotator. If there was some documentation I had overlooked please let me know, otherwise any insight is much appreciated.

Thank you as always

I am using GATK 3.3-0 HaplotypeCaller for variant calling. When I run HaplotypeCaller with the command

java -jar GenomeAnalysisTK.jar -T HaplotypeCaller -R all_chr_reordered.fa -I 30_S30.bam --genotyping_mode DISCOVERY -stand_emit_conf 10 -stand_call_conf 50 -o 30_S30_control1.vcf -L brca.intervals

I get all the variants I want, however, I also want to get the number of forward and reverse reads that support REF and ALT alleles. Therefore I use StrandBiasBySample annotation when running HaplotypeCaller with the command:

java -jar GenomeAnalysisTK.jar -T HaplotypeCaller -R all_chr_reordered.fa -I 30_S30.bam --genotyping_mode DISCOVERY -stand_emit_conf 10 -stand_call_conf 50 -o 30_S30_control2.vcf -L brca.intervals -A StrandBiasBySample

The SB field is added, but a variant that was in 30_S30_control1.vcf is absent in 30_S30_control2.vcf. All the remaining variants are there. The only difference between two variant calls was adding -A StrandBiasBySample. What I'm wondering about is that why this one variant is absent.

the missing variant: 17 41276152 . CAT C 615.73 . AC=1;AF=0.500;AN=2;BaseQRankSum=0.147;ClippingRankSum=0.564;DP=639;FS=15.426;MLEAC=1;MLEAF=0.500;MQ=60.00;MQ0=0;MQRankSum=-1.054;QD=0.96;ReadPosRankSum=0.698;SOR=2.181 GT:AD:DP:GQ:PL 0/1:565,70:635:99:653,0,18310

So I decided to run HaplotypeCaller without -A StrandBiasBySample and later add the annotations with VariantAnnotator. Here is the command:

java -jar GenomeAnalysisTK.jar -T VariantAnnotator -R all_chr_reordered.fa -I 30_S30.bam --variant 30_S30_control1.vcf -L 30_S30_control1.vcf -o 30_S30_control1_SBBS.vcf -A StrandBiasBySample

However, the output vcf file 30_S30_control1_SBBS.vcf was not different from the input variant file 30_S30_control1.vcf except for the header, SB field wasn't added. Why was the SB field not added? Is there any other way to get the number of forward and reverse reads?

Please find 30_S30_control1.vcf, 30_S30_control2.vcf and 30_S30_control1_SBBS.vcf in attachment

I have constructed a VCF using GenotypeGVCFs. Due to downsampling and filtering imposed by HaplotypeCaller/GenotypeGVCFs, four fields of interest within the VCF do not reflect the data that went into building the file. I would like to update a these fields to reflect all read data used in the pipeline, but I have been able to do so for just 3 of the 4. I have been able to update INFO MQ0, INFO DP, and sample-level (FORMAT) AD, but I have not been able to update sample-level (FORMAT) DP.

I have run VariantAnnotator as follows.



java -Xmx10g \
  -jar $gatk \
  -T VariantAnnotator \
  -R $ref \
  -L $inVCFfn \
  --variant $inVCFfn \
  --dbsnp $dbsnp \
  --out $outVCFfn \
  --annotation Coverage \
  --annotation DepthPerAlleleBySample \
  --annotation MappingQualityZero \
  [-I fileName.1.bam … -I fileName.810.bam]

The documentation for --annotation Coverage indicates that it should update both the INFO DP and the sample-level (FORMAT) DP, but the sample-level update seems not to be occurring. For example:

$ awk '($2==7157834) { print $9, "|", $53 }' raw.vcf
GT:AD:DP:GQ:PL | 0:4,0:4:99:0,135

$ awk '($2==7157834) { print $9, "|", $53 }' raw.annotated.vcf
GT:AD:DP:GQ:PL | 0:131,0:4:99:0,135

(Aside: I'm working with a haploid chromosome, hence the single-value GT and two-value AD and PL fields). Although AD was updated from "4,0" to "131,0", the sample-level "DP" remained at "4". Of course I could approximate DP as the sum of AD values, but since AD is pre-filter and sample-level DP is post-filter, this wouldn't quite be correct. I should note that when I run HaplotypeCaller/GenotypeGVCFs on a subset of the data, the sample-level DP values are very close to the sum of AD's, so it's not a matter of most reads being filtered out, but rather that they have been downsampled. Am I missing something?

Thanks! David

P.S. The INFO field DP and MQ0 are indeed updated as expected:

$ awk '($2==7157834) { print $8 }' raw.vcf

$ awk '($2==7157834) { print $8 }' raw.annotated.vcf

I was wondering if there is a nice way to apply multiple processing steps to each variant (or a group of variants) as they are read so that the variant file is not read again and again. My understanding is that even if I use Queue, each script would read the vcf again. Is that correct?

Version 3.1.1. Human normal samples.

I couldnt find AlleleBalance and AlleleBalanceBySample tags in my vcf outputs. Tags are not found even for single variant I tried HaplotypeCaller with -all or directly with -A AlleleBalance or -A AlleleBalanceBySample. Also I tried Variantannotator with -all or -A AlleleBalance or -A AlleleBalanceBySample.

GATK Team,

First of all, I'm very excited about v3.x GATK, you guys and gals on the GATK Team are doing awesome work!

I have a question: How do I get CombineGVCFs to forward the sample-level annotations calculated by HC with the --emitRefConfidence GVCF option enabled? I tried passing the same annotation flags to CombineGVCFs that I passed to HC, but none of the annotations beyond the standard set were incorporated. Annotations such as StrandBiasBySample require access to the underlying reads and forwarding these annotations to the CombineGVCFs output would be less prohibitive than running VariantAnnotator on my 20 WGS datasets...

I have annotated my vcf file of 20 samples from Unified genotyper using the following steps.

Unified genotyper->Variantrecalibration->Applyrecalibration->VariantAnnotator

My question is how should I proceed if I have to select rare variants (MAF<1%) for the candidate genes that I have,for each of these 20 samples?

Hi, I have a tiny, 5000-line VCF file that I want to add dbSNP annotations to. I'm surprised to see VariantAnnotator iterating along the millions of records in the dbSNP file, rather than the 5000 variants in the input VCF file. This will take 42mins on dbsnp 137...

Am I misunderstanding how this tool works, or just using it wrongly?

Hi, We use GATK with snpEff to annotate variants of our WES experiments. We use VariantAnnotator to keep only the effect with highest impact. We've realized that for some experiments it could be useful for us to customize priorities assignment (i.e. if a variant is categorized both as DOWNSTREAM for a gene and INTRON for the adjacent gene, the effect picked by default is DOWNSTREAM while we'd like to keep INTRON, etc.) Is there a way to modify VariantAnnotator default behaviour?

Could you tell me how to encourage GATK to annotate my genotype columns (i.e. add annotations to the FORMAT and PANC_R columns in the following file):

It used to be possible to annotate a VCF files using multiple VCF track files. Basically the --comp command could be used multiple times. Now only the last track gets annotated. That means, if I use "-T VariantAnnotator --comp:TR1 tr1.vcf --comp:TR2 tr2.vcf, only the TR2 flag is used for annotation, and the TR1 flag is not. This is inconsistent and must be a recent regression.

It works fine with GenomeAnalysisTK-2.5-2 but it doesn't work anymore with GenomeAnalysisTK-2.6-2.

I am writing a pipeline to analyse exome sequencing data from families and would like some advice on using the VariantAnnotator walker. It seems I need to use VariantAnnotator prior to VariantRecalibrator as the latter relies on annotations generated by VariantAnnotator. Is this correct? Also, I would like to annotate my VCF using SNPeff and SNPsift. Can you suggest the best order in which to perform these steps. For example, my plan at the moment is to run steps in the following order: HaplotypeCaller, VariantAnnotator, VariantRecalibrator, ApplyRecalibration, PhaseByTransmission, ReadBackedPhasing, SNPeff, SNPsift.

Any help would be much appreciated,

Does the order of the args of the bam files need to correspond to the order of the samples columns in the vcf?

I just run HyplotypeCaller on a dataset. For the same dataset, I have run through Unified genotyper and then directly subjected the raw vcf from UG to VQSR step without the help of VariantAnnotator before and get through VQSR without any problem. However, when I try to subject the raw callset derived from HyplotypeCaller directly to VQSR step, the VQSR module complained about it and error message is below:


ERROR MESSAGE: Bad input: Values for HaplotypeScore annotation not detected for ANY training variant in the input callset. VariantAnnotator may be used to add these annotations. See


So after HyplotypeCaller, the derived vcf file needs to run though VariantAnnotator? Since Unified genotyper derived callset does not need the help of VariantAnnotator (all annotations needed for VQSR are included after UG), it seems not the case for HyplotypeCaller? I can run through VariantAnnotator for HyplotypeCaller derived vcf file, just want to make sure if my understanding is correct?

Thanks and best

I have a set of VCFs with identical positions in them:

VCF4: 1 10097 . T . 15.56 . AN=134;DP=1348;MQ=18.22;MQ0=442 GT:DP

If I use all of them as input for VariantRecalibrator, which annotations will VariantRecalibrator use? Should I instead merge the VCFs with CombineVariants and run VariantAnnotator, before I run VariantRecalibrator?

I'm not sure if the forum is for asking technical questions only or you are allowed to ask for best practices as well. Feel free to delete my question, if it doesn't belong here. Thank you.

I am trying to filter some of my high-coverage samples based on a minimum depth and have found that the value stored in the DP INFO field and the AD genotype tag changes depending on whether or not I have run VariantAnnotator. The call I have used for VariantAnnotator is:

Raw BAM, version 2.4-9

Annotated: DP=2745, AD=4,2729 Raw: DP=616, AD=1,611

I suspect what is happening here is that VariantAnnotator is taking the depth information from the provided BAM and replacing the depth information reported by the variant caller. Anyway, just wondering- which value is a better reflection of the depth used to make a given variant call? (i.e. which could I use in hard filtering?)

Thanks for your help!

I ran the HaplotypeCaller, VariantAnnotator, and Variant Validatoor on chr3 locations from a human tumor sample.

The HaplotypeCaller command line is:

#Fasta from the gz in the resource bundle

java -Xms1g -Xmx2g -jar $gatk -R ${indx} -T HaplotypeCaller \
 -I chrom_bams/286T.chr3.bam \
 -o hapc_vcfs/286T.chr3.raw.vcf 

The VariantAnnotator command line is:

    --variant:vcf hapc_vcfs/286T.chr3.raw.vcf \
    --out varanno_vcfs/286T.chr3.va.vcf

This all works nicely, but I go back and use ValidateVariants just to be sure:

java -Xms1g -Xmx2g -jar $gatk -R ${indx} -T ValidateVariants \
   --dbsnp ${dbsnp} \
   --variant:vcf varanno_vcfs/286T.chr3.va.vcf \

    2> report/ValidateVariants/286T.chr3.va.valid.err &

An issue arises with a rsID that is flagged as not being present in dbSNP.

...fails strict validation: the rsID rs67850374 for the record at position chr3:123022685 is not in dbSNP

I realize this is an error message that generally would not generally qualify as an issue to post to these forums, however it is an error that seems to be generated by the Haplotype caller, illuminated by VariantAnnotator, and caught by the ValidateVariants.

The first 7 fields of the offending line in the 286T.chr3.va.vcf can be found using: cat 286T.chr3.va.vcf | grep rs67850374

chr3    123022685       rs67850374;rs72184829   AAAGAGAAGAGAAGAG        A       1865.98 .

There is a corresponding entry in the dbsnp_135.hg19.vcf file: cat $dbsnp | grep rs67850374

chr3    123022685       rs67850374;rs72184829   AA      A,AAAGAGAAGAG,AAAGAGAAGAGAAGAGAAGAG     .  PASS

My initial guess is that this is caused by a disagreement in the reference and variant fields between the two annotations. From what I can gather the call to the variantcontext function validateRSIDs() has a call to validateAlternateAlleles(). I assume this is what throws the error that is then caught and reported as "...fails strict validation..."

The UCSC genome browser for hg19 does show the specified position to be AA. It seems as thought the HaplotypeCaller simply used a different reference than dbsnp in this case.

The reference file supplied to HaplotypeCaller was the same as to VariantAnnotator and ValidateVariants. I did not supply the dbsnp argument to the HaplotypeCaller as I planned on doing all annotations after the initial variant calling, and the documentation states that the information is not utilized in the calculations. It seems as though this is a difference in between the reference assembly for dbSNP and the the reference supplied by the resource bundle.

My questions are:

  1. Is this really a problem that arises from slightly different reference assemblies?
  2. Is the hg19-1.5 reference fasta different from any other hg19 reference fasta?
  3. Is there at tool that I have missed that would have prevented this error and allowed the pipeline to continue without error?"
  4. Will this strict validation failure cause problems for the VariantRecalibrator?

As it stands, I am simply going to discard the offending lines manually. There are less than twenty in the entire exome sequencing of this particular tumor-normal sequencing. However, it seems like this issue will likely arise again. I will check the dbSNP VCF for places where the reference differs from the sequence in hg19. At least that should give me an estimate of the number of times this will arise and the locations to exclude from the variant calls.

I would like to have certain annotations applied only if the variants in the resource and the target have the same genomic change. Ex: In Cosmic the following variants are present.

However, in my VCF file I get the G12A annotation for all variants at this site even if the actual change is G12V or G12D.

Is this possible?

Unfortunately I've gottent stuck and I'm trying to figure out why Variant Annotator wouldn't be annotating INDELs with MappingQualityRankSumTest and ReadPosRankSumTest, it seems to annotate SNPs fine. There are both Homs and het's called on the sample. Could it be I need to left align the indels to get enough coverage? What would you suggest is the best way to debug this? Is there a way to make GATK behave more verbosely about why it's refusing an annotation?

Thanks Martin

I had annotated raw indel file (given by UnifiedGenotyper), 1000G_omni2.5.b37.sites.vcf and hapmap_3.3.b37.sites.vcf with all possible annotations including QD (QualByDepth) using VariantAnnotator. However, i got an error when i tried to run VariantRecalibrator. It was complaing that QD has not been found in training variant. Is QD important annotation for indel filtering. Can it be ignored ?

P.S. - i did not use sample bam file while annotating training data set.

Hi there, I'm running into an issue with my Queue pipeline, with variants called with HaplotypeCaller. Once I get the raw VCF file, I use VariantAnnotator before VQSR: however, no HaplotypeScore annotation is being produced, resulting in a failure of the VariantRecalibrator step where 'HaplotypeScore' was indicated as an annotation.

I tried to correct the issue by indicating to VariantAnnotator to use all annotations

  class AnnotationArguments (t: Target) extends VariantAnnotator with UNIVERSAL_GATK_ARGS {
this.reference_sequence = qscript.referenceFile
// Set the memory limit to 7 gigabytes on each command.
    this.memoryLimit = 7
    this.input_file :+= qscript.bamFile
    this.D = qscript.dbSNP_b37

But I still can't get any output in the annotated VCF of that parameter. Here an example of a variant


Any suggestions on what I might be doing wrong?

thanks very much for your help, Francesco

Could you tell me when we can use new version of SnpEff with GATK?

I have some bugs :

I don't know if I forget some other options linked these annotations. These options are important for me. So I deleted them but if somebody want to use them ...

I am trying to understand how Variant Annotator functions. I took the vcf file from the output of UnifiedGenotyper and ran Variant Annotator with the same .bam and .bed files I used for running UnifiedGenotyper. I expected that all the calculations in the INFO field will remain the same, since I am using the same input files. However, I find that some fields have different values. Here is an example: UnifiedGenotyper output:

chr22   30094366        .       G       A       172.01  .       AC=1;AF=0.500;AN=2;BaseQRankSum=3.182;DP=244;DS;Dels=0.00;FS=0.000;HaplotypeScore=118.5897;MLEAC=1;MLEAF=0.500;MQ=43.29;MQ0=0;MQRankSum=-0.049;QD=0.70;ReadPosRankSum=1.428;SB=-6.201e+01        GT:AD:DP:GQ:PL  0/1:220,19:244:99:202,0,2693 

VariantAnnotator output:

chr22   30094366        .       G       A       172.01  .       ABHet=0.923;AC=1;AF=0.500;AN=2;BaseQRankSum=3.182;DP=993;DS;Dels=0.00;FS=0.000;HaplotypeScore=454.8386;MLEAC=1;MLEAF=0.500;MQ=43.29;MQ0=0;MQ0Fraction=0.0000;MQRankSum=-0.378;OND=0.034;QD=0.17;ReadPosRankSum=-4.859;SB=-6.201e+01      GT:AD:DP:GQ:PL  0/1:220,19:244:99:202,0,2693

I am running GATKLite 2.1. Notice the DP in the info field has a different value. HaplotypeScore, QD, MQRankSum, etc have different values as well. Am I doing anything wrong? Shouldn't these values be the same when I recalculate these fields using VariantAnnotator?
