Hi all,
just curious to know what exactly means that for certain SNPs we read ""NO CALL" on our vcf file, despite not been filtered out?

thanks

    Hi Irene,

    ./. or no-call genotypes occur when the tool does not have enough information to make a proper genotype call. This could be due to low coverage or bad quality data or messy regions in general.
