I have a file for example:
SNP TOP1&2 AB1&2 SNP1 GG BB SNP2 CC AA SNP3 GG BB . . SNP6 AC AB SNP7 CC BB SNP8 AA AA
Can someone explain me why first CC is AA in AB format, and another CC is BB? If I understand correctly, it is about the preceding and the following SNPs? Is there a map somewhere available? Or could someone write this to me, to check if I am translating correctly TOP1 TOP2 translators on AB1 AB2?
