--- layout: default navsection: userguide title: "Using GATK with Arvados" ... This tutorial demonstrates how to use the Genome Analysis Toolkit (GATK) with Arvados. In this example we will install GATK and then create a VariantFiltration job to assign pass/fail scores to variants in a VCF file. {% include 'tutorial_expectations' %} h2. Installing GATK Download the GATK binary tarball[1] -- e.g., @GenomeAnalysisTK-2.6-4.tar.bz2@ -- and "copy it to your Arvados VM":{{site.baseurl}}/user/tutorials/tutorial-keep.html.
~$ arv keep put GenomeAnalysisTK-2.6-4.tar.bz2

Next, you need the GATK Resource Bundle[2]. This may already be available in Arvados. If not, you will need to download the files listed below and put them into Keep.

h2. Submit a GATK job The Arvados distribution includes an example crunch script ("crunch_scripts/GATK2-VariantFiltration":https://arvados.org/projects/arvados/repository/revisions/master/entry/crunch_scripts/GATK2-VariantFiltration) that runs the GATK VariantFiltration tool with some default settings.
