Test-drive the GATK tools and Best Practices pipelines on Terra
Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.
We will be out of the office on November 11th and 13th 2019, due to the U.S. holiday(Veteran's day) and due to a team event(Nov 13th). We will return to monitoring the GATK forum on November 12th and 14th respectively. Thank you for your patience.
What do sites labeled "." in FILTER field mean (after running VQSR)?
After using VQSR, I have a vcf output that contains sites labeled "." in the FILTER field. When I look at the vcf documentation (1000 genomes), it says that those are sites where filters have not been applied. Is this correct? I would like to know more about what these sites mean, exactly.
An example of such a site in my data is:
1 10439 . AC A 4816.02 . AC=10;AF=0.185;AN=54;BaseQRankSum=-4.200e-01;ClippingRankSum=-2.700e-01;DP=1690;FS=6.585;GQ_MEAN=111.04;GQ_STDDEV=147.63;InbreedingCoeff=-0.4596;MLEAC=17;MLEAF=0.315;MQ=36.85;MQ0=0;MQRankSum=-8.340e-01;NCC=0;QD=11.39;ReadPosRankSum=-8.690e-01;SOR=1.226 GT:AD:DP:GQ:PGT:PID:PL 0/1:22,14:36:99:0|1:10439_AC_A:200,0,825 0/0:49,0:49:0:.:.:0,0,533 0/0:92,0:92:0:.:.:0,0,2037 0/1:20,29:49:99:.:.:634,0,340 0/0:11,0:16:32:.:.:0,32,379 0/1:21,17:38:99:.:.:273,0,616 0/0:57,0:57:0:.:.:0,0,1028 0/0:58,0:58:0:.:.:0,0,1204 0/0:52,0:52:0:.:.:0,0,474 0/0:86,0:86:27:.:.:0,27,2537 0/1:13,24:37:99:.:.:596,0,220 0/1:14,34:48:99:.:.:814,0,263 0/0:86,0:86:0:.:.:0,0,865 0/0:61,0:61:0:.:.:0,0,973 0/0:50,0:50:0:.:.:0,0,648 0/0:40,0:40:0:.:.:0,0,666 0/0:79,0:79:0:.:.:0,0,935 0/0:84,0:84:0:.:.:0,0,1252 0/1:22,27:49:99:.:.:618,0,453 0/0:39,0:39:0:.:.:0,0,749 0/0:74,0:74:0:.:.:0,0,1312 0/1:13,18:31:99:.:.:402,0,281 0/0:41,0:44:99:.:.:0,115,1412 0/1:30,9:39:99:.:.:176,0,475 0/1:26,23:49:99:.:.:433,0,550 0/1:13,34:47:99:.:.:736,0,185 0/0:44,0:44:0:.:.:0,0,966
