why new version mutect2 output vcf add DP?
I find the result of mutect2 in gatk18.104.22.168 differs from 22.214.171.124 in vcf structure.
why this need a change? and for example in new version
GT:AD:AF:DP: the value is 0/1:31,34:0.522:65:
but I once read something in somatic vcf, the first value of AD does not stands for ref reads, is it true, thanks a lot.
and can you tell me AF is usually smaller or bigger then the value in AD(I mean first /(first + second), here 34/(31+34))
