In a VCF file, when DP=0, why it stills give a Genotype?
I am dealing with my data using vcftools, in the generated vcf file, I found that when DP=0, why it stills give a Genotype, like 0/1 0/0 or something? I attached a pic, a screenshot from a vcf file. there are 2 lines showed DP=0,and still have a GT value! The question bothered me for a long time, HELP!!!
