Hi all,

I want to use 1000Genomes as control population for a small case-case control study. Now I want to be sure that the genotypes from 1000Genomes are good so I wanted to know what the Coverage/Read Depth is for a few SNPs that I want to test. Is there an easy way to figure this out?

Any tips or hints are very welcome!

Check if you SNPs are present in one of the individual call sets here (e.g. si, ox or bc):

ftp://ftp-trace.ncbi.nih.gov/1000genomes/ftp/technical/working/20130723_phase3_wg/

They have read depth info in VCFs.

bc = ALL.chr4.bc.20130502.snps_indels_mnps_complex.genotypes.vcf.gz ox = ALL.chr4.oxford_platypus.20130502.snps_indels_mnps_cplx.low_coverage.genotypes.vcf.gz si = ALL.chrom4.samtools.20130502.snps_indels.low_coverage.genotypes.vcf.gz

So if the SNP is in there they are bad? I was hoping to filter variants on a read depth of 20 more or less..
