EXPERIMENTAL FilterVariantTranches

Apply tranche filtering

Category Variant Evaluation and Refinement

Overview

Apply tranche filtering to VCF based on scores from the INFO field.

Inputs

The input variants to tranche filter.
snp-truth-vcf A VCF containing known common SNP sites
indel-truth-vcf A VCF containing known and common INDEL sites.
info-key The key from the INFO field of the VCF which contains the values that will be used to filter.
tranche List of percent sensitivities to the known sites at which we will filter. Must be between 0 and 100.

Outputs

A tranche filtered VCF.

Usage example

Apply tranche filters based on CNN_1D scores

 gatk FilterVariantTranches \
   -V input.vcf.gz \
   --snp-truth-vcf hapmap.vcf \
   --indel-truth-vcf mills.vcf \
   --info-key CNN_1D \
   --tranche 99.9 --tranche 99.0 --tranche 95 \
   --max-sites 8000 \
   -O filtered.vcf

Argument name(s)	Default value	Summary
Required Arguments
--indel-truth-vcf	null	Input file of known common INDEL sites.
--output -O	null	Output VCF file

Optional Tool Arguments
--arguments_file	[]	read one or more arguments files and add them to the command line
--gcs-max-retries -gcs-retries	20	If the GCS bucket channel errors out, how many times it will attempt to re-initiate the connection
--help -h	false	display the help message
