Hello!

So I have a matrix like so

   SNP
Allele  C/G    A/C    C/G
1       0      1      1
2       0      0      1
3       0      1      0

of snps in alleles (1,2,3,ect...I have 20) and then a file of samples containing the haplotypes (eg. sample A has haplotype 1 and 2) and want to convert this to a genotype matrix for genetic association. Does anyone know how I could do this? So I would have a matrix like

   SNP
Sample    C/G    A/C    C/G
A         0      1      1
B         0      0      1
C         0      2      0

Where 2 would be heterozygous etc

Would really appreciate the help, been stuck on this for days!
