4 title: "Tutorial: GATK VariantFiltration"
8 h1. Tutorial: GATK VariantFiltration
10 Here you will use the GATK VariantFiltration program to assign pass/fail scores to variants in a VCF file.
14 * Log in to a VM "using SSH":ssh-access.html
15 * Put an "API token":api-tokens.html in your @ARVADOS_API_TOKEN@ environment variable
16 * Put the API host name in your @ARVADOS_API_HOST@ environment variable
18 If everything is set up correctly, the command @arv -h user current@ will display your account information.
20 h3. Get the GATK binary distribution.
22 Download the GATK binary tarball[1] -- e.g., @GenomeAnalysisTK-2.6-4.tar.bz2@ -- and copy it to your Arvados VM.
27 arv keep put --in-manifest GenomeAnalysisTK-2.6-4.tar.bz2

36 h3. Get the GATK resource bundle.
38 This can take a while to download, and should already be available in Arvados. For now let's just list the files and sizes, to make sure we have the correct collection ID.
41 arv keep ls -s d237a90bae3870b3b033aea1e99de4a9+10820+K@qr1hi
47 50342 1000G_omni2.5.b37.vcf.gz
48 1 1000G_omni2.5.b37.vcf.gz.md5
49 464 1000G_omni2.5.b37.vcf.idx.gz
50 1 1000G_omni2.5.b37.vcf.idx.gz.md5
51 43981 1000G_phase1.indels.b37.vcf.gz
57 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.
59 We will pass it the following parameters:
61 * input -- a collection containing the source VCF data. Here we will use an exome report from PGP participant hu34D5B9.
62 * gatk_binary_tarball -- a collection containing the GATK 2 tarball.
63 * gatk_bundle -- a collection containing the GATK resource bundle[2].

87 Note the job UUID in the API response.
89 h3. Monitor job progress
91 There are three ways to monitor job progress:
93 # Go to Workbench, drop down the Compute menu, and click Jobs. The job you submitted should appear at the top of the list. Hit "Refresh" until it finishes.
94 # Run @arv -h job get --uuid JOB_UUID_HERE@ to see the job particulars, notably the "tasks_summary" attribute which indicates how many tasks are done/running/todo.
95 # Watch the crunch log messages and stderr from the job tasks:
98 curl -s -H "Authorization: OAuth2 $ARVADOS_API_TOKEN" \
99 https://{{ site.arvados_api_host }}/arvados/v1/jobs/JOB_UUID_HERE/log_tail_follow
