Bug Bulletin: we have identified a bug that affects indexing when producing gzipped VCFs. This will be fixed in the upcoming 3.2 release; in the meantime you need to reindex gzipped VCFs using Tabix.

I have been trying to find documentation for understanding the annotations and numbers in the VCF file. Something like below, can someone guide me how to understand/interpret the numbers? How is the quality of the variant calling for this particular indel?

AC=2; AF=0.100; AN=20; BaseQRankSum=6.161; ClippingRankSum=-2.034; DP=313; FS=5.381; InbreedingCoeff=-0.1180; MLEAC=2; MLEAF=0.100; MQ=58.49; MQ0=0; MQRankSum=-0.456; QD=1.46; ReadPosRankSum=-4.442; VQSLOD=0.348; topculprit=ReadPosRankSum
