What is the best way to work out ancestry from array data such as this:

    Sample ID   SNP Name    Chr Position    Allele1 - Top   Allele2 - Top   B Allele Freq   Log R Ratio
7512498063_R04C01   rs2661837   6   160790174   C   C   0.0000  0.0863

7512498063_R04C01   rs1492138   12  22030178    A   A   0.0000  -0.0156

7512498063_R04C01   rs206018    6   32177880    G   G   0.9890  0.2482
7512498063_R04C01   rs11929668  3   119535795   G   G   0.9837  -0.0526
7512498063_R04C01   rs4252072   6   161128264   A   A   0.0000  -0.1592

Are there tools available to work out where each SNP is most common and therefore predict ancestry?

I think peddy comes close to what you are looking for, not sure how many SNPs you have and therefore if it's truly applicable.

Thanks for the suggestion. The data is from arrays, so about 2.3 million SNPs. The only problem is peddy seems to take a vcf file and my data is in the format above so I would need another tools to convert? Are you aware of any? Thanks again
