How can I set genotype HOM=0 (no mater it is wild type or mutation) and HET=1?

Hi Wei Zhou

how do I treat Genotype in different ways like the plink shown below, basically, I am interested in homozygotes vs. heterozygotes, how can I set genotype HOM=0 (no mater it is wild type or mutation) and HET=1?

thanks
