I am trying to get the alleles and frequences of some SNPs (from across the genome) for the assembly 37:GRCh37 (positive strand). I thought the easiest way would be to download the frequency data from hapmap and then look for my SNPs, but they are only have data for up to build 36. I also tried to send a batch query at the ncbi data but they dont support files as large as mine(I have to cut it in chunks) and they return far too much information than I need (genotypes for all submitted data, all existing populations, etc). Im only interested in CEU and the frequences from HapMap are more than good enough for my purposes. Im thinking there must be an easier way to do it than the batch query. All ideas are welcome!
