I have a set of SNPs (500 SNPs), I would like to get MAF (minor allele frequency) for them besed on 1000 Genome for each population (Europe, Africa , America, and ...).
I can find them by searching each SNPs separately and also using BioMart but I would like to get for each population.
If there is a way for finding it preferably using R, please help me.
hi, I have not used R/BioC package, but if you go to the UCSC Table Browser, then the 1000G data (1000g phase 3 vars track) looks like this - http://s11.postimg.org/6n8fe7m37/Screen_Shot_2016_03_09_at_13_55_36.png
Since your list is just 500, you could easily use Table Brwsr utility to get the data and then basically parse the allele freq. in the Info col.
Thanks a lot for your help, But would you please help me how can I put 1000G as track.
See thsi setting,
And you could use identifiers to provide your SNP list.
