   7 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.

  13 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.

  21 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.
