Hi, I got a file with three columns. One is an rs id, others are Allele1 and Allele2. Alleles are presented as nucleotides:
A,G G,C G,G ect.
I need to create a file with AB Illumina format... so I need to convert AG, GC, GG to AB, AA or BB (depends). Can someone explain to me the best way to do that? And it's even possible having only that information what have I?
