**What it does**

Filters variant calls using a number of user-selectable, parameterizable criteria.

For more information on using the VariantFiltration module, see this `tool specific page &lt;http://www.broadinstitute.org/gatk/gatkdocs/org_broadinstitute_sting_gatk_walkers_filters_VariantFiltration.html&gt;`_.

To learn about best practices for variant detection using GATK, see this `overview &lt;http://www.broadinstitute.org/gatk/guide/topic?name=best-practices&gt;`_.

If you encounter errors, please view the `GATK FAQ &lt;http://www.broadinstitute.org/gatk/guide/topic?name=faqs&gt;`_.

**Inputs**

GenomeAnalysisTK: VariantFiltration accepts a VCF input file.


**Outputs**

The output is in VCF format.

Go `here &lt;http://www.broadinstitute.org/gatk/guide/topic?name=intro&gt;`_ for details on GATK file formats.

-------

**Settings**::


 filterExpression                                     One or more expression used with INFO fields to filter (see wiki docs for more info)
 filterName                                           Names to use for the list of filters (must be a 1-to-1 mapping); this name is put in the FILTER field for variants that get filtered
 genotypeFilterExpression                             One or more expression used with FORMAT (sample/genotype-level) fields to filter (see wiki docs for more info)
 genotypeFilterName                                   Names to use for the list of sample/genotype filters (must be a 1-to-1 mapping); this name is put in the FILTER field for variants that get filtered
 clusterSize                                          The number of SNPs which make up a cluster (see also --clusterWindowSize); [default:3]
 clusterWindowSize                                    The window size (in bases) in which to evaluate clustered SNPs (to disable the clustered SNP filter, set this value to less than 1); [default:0]
 maskName                                             The text to put in the FILTER field if a 'mask' rod is provided and overlaps with a variant call; [default:'Mask']
 missingValuesInExpressionsShouldEvaluateAsFailing    When evaluating the JEXL expressions, should missing values be considered failing the expression (by default they are considered passing)?
