Accelerated variant filtration based on conditions. Filters a VCF using a boolean expression. variantfiltration can only filter on INFO annotations, not on FORMAT.


$ pbrun variantfiltration \ --in-vcf sample.vcf \ --out-file output.vcf \ --expression "QD < 2.0 || ReadPosRankSum < -20.0" \ --filter-name FILTER


gatk VariantFiltration -V sample.vcf \ -O output.vcf \ --filter-expression "QD < 2.0 || ReadPosRankSum < -20.0" \ --filter-name FILTER

Filter a VCF using a boolean expression.

Input/Output file options

--in-vcf IN_VCF

Path to the input VCF file. (default: None)

Option is required.

--out-file OUT_FILE

Path to the output file with an extension of either '.vcf' or '.csv' (default: None)

Option is required.

Tool Options:

-m MODE, --mode MODE Type of variants to include in the filter. Possible

values are {SNP, INDEL, BOTH}. (default: BOTH)


Boolean expression for filtering variants (e.g. '--expression "QD < 2.0 || ReadPosRankSum < -20.0 || InbreedingCoeff < -0.8 || FS > 200.0"). (default: None)

Option is required.

--filter-name FILTER_NAME

Field value for variants that pass the filter expression. (default: None)

Option is required.

Common options:

--logfile LOGFILE

Path to the log file. If not specified, messages will only be written to the standard error output. (default: None)

--tmp-dir TMP_DIR

Full path to the directory where temporary files will be stored.

--with-petagene-dir WITH_PETAGENE_DIR

Full path to the PetaGene installation directory. By default, this should have been installed at /opt/petagene. Use of this option also requires that the PetaLink library has been preloaded by setting the LD_PRELOAD environment variable. Optionally set the PETASUITE_REFPATH and PGCLOUD_CREDPATH environment variables that are used for data and credentials (default: None)


Do not delete the directory storing temporary files after completion.

--license-file LICENSE_FILE

Path to license file license.bin if not in the installation directory.


Do not override seccomp options for docker (default: None).
