Validates a VCF file with an extra strict set of criteria.
ValidateVariants is a GATK tool that takes a VCF file and validates much of the information inside it. In addition to standard adherence to the VCF specification, this tool performs extra checks to make ensure the information contained within the file is correct. Checks include the correctness of the reference base(s), accuracy of AC & AN values, tests against rsIDs when a dbSNP file is provided, and that all alternate alleles are present in at least one sample. If you are looking simply to test the adherence to the VCF specification, use --validationType NONE.
A variant set to validate.
java -Xmx2g -jar GenomeAnalysisTK.jar \ -R ref.fasta \ -T ValidateVariants \ --variant input.vcf \ --dbsnp dbsnp.vcf
These Read Filters are automatically applied to the data by the Engine before processing by ValidateVariants.
This tool applies the following downsampling settings by default.
This tool uses a sliding window on the reference.
The arguments described in the entries below can be supplied to this tool to modify its behavior. For example, the -L argument directs the GATK engine restricts processing to specific genomic intervals (this is an Engine capability and is therefore available to all GATK walkers).
This table summarizes the command-line arguments that are specific to this tool. For more details on each argument, see the list further down below the table or click on an argument name to jump directly to that entry in the list.
|Argument name(s)||Default value||Summary|
|NA||Input VCF file|
|ALL||which validation type to run|
||false||skip validation on filtered records|
||false||just emit warnings on errors instead of terminating the run at the first instance|
Arguments in this list are specific to this tool. Keep in mind that other arguments are available that are shared with other tools (e.g. command-line GATK arguments); see Inherited arguments above.
skip validation on filtered records
By default, even filtered records are validated.
which validation type to run
The --validationType argument is an enumerated type (ValidationType), which can have one of the following values:
Input VCF file
Variants from this VCF file are used by this tool as input. The file must at least contain the standard VCF header lines, but can be empty (i.e., no variants are contained in the file).
just emit warnings on errors instead of terminating the run at the first instance
