Here is a VCF line directly from the Samtools variant calling pipeline (no varfilter.pl) for one exome:
chr1 156713512 . C T 60.5 . **DP=6**;AF1=1;AC1=2;DP4=0,0,4,0;MQ=34;FQ=-39 GT:PL:**DP**:SP:GQ 1/1:93,12,0:**4**:0:21
I noticed that the genotype column has a depth of 12 listed (highlighted: **). How can this be if DP=6? What am I missing?
