Dear all, I used samtools for SNPs calling and vcftools for SNPs filtering. I got a vcf file with a lot SNPs.How to interpret the genotypes when DP=1? In my opinion, DP=1 means that this site has only one read, it could be homozygous 0/0 or 1/1, but how can it be a heterozygous 0/1?
The following is what I have observed in my vcf file.
Thanks for your attentions! Please help!
