Hello,
i wish to compare the allelic frequencies of SNPs extracted from HAPMAP PROJECT between populations, i take always into consideration the GMAF extracted from dbSNP, but sometimes i find for example for SNP X A/G G ancestor GMAF T, when i wish to compare between for example ASIAN and European populations, i find for the first one GMAF G allele, for the second population T allele what can i do in this case ? Please Look at the link below (rs7214)/Shall i look at the Affymetrix LINK (+ /- chromosomal strand..)
