Hello everyone

I have snp's data from VarScan like

#CHROM     POS   ID     REF    ALT    QUAL    FILTER    INFO    FORMAT    Sample1
    chr1       12198    .      G        C          .           PASS    ADP=54;WT=0;HET=1;HOM=0;NC=0
    chr1       12783    .      G        A          .           PASS    ADP=58;WT=0;HET=1;HOM=0;NC=0
    chr1       13116    .      T        G          .           PASS    ADP=30;WT=0;HET=1;HOM=0;NC=0

could you please help me to convert the SNP's to 0,1,2?

Thank you so much in advance
