Hi,

I have a raw Affymtrix SNP data that I will like to convert to Plink and VCF formats. The columns of my data are as follows:

"Probe ID","Affy SNP ID", "dbSNP RS ID","Chromosome","Physical Position","Position End","Strand","ChrX", "Allele A","Allele B","Ref Allele","Alt Allele"  etc.

I'm new to genetics and gwas analysis. Can someone please advise me on what to do.
