Hello, I am wondering why, if I have used the -v option in bcftools (output only variant sites), I have in the output some reference homozygotes. Could it be because the genotype likelihood is too low that could be also a het? Does the -v option look at the most probable genotype (the one written down) or at the genotype likelihoods?

bcftools view -Svc myfile.vcf.gz
