The Phase 1 of the 1000Genomes data has published genotypes from about 1,092 individuals, and made them available in their FTP server: ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/phase1/analysis_results/integrated_call_sets/
So far, I was always convinced that these files contain only SNPs that are present in all the populations. For example, I thought that SNPs present only in the European population ("private" to Europeans) would be filtered out from this dataset.
The problem is that I can't find any reference or README file confirming me that the VCF files in 1000 Genomes refer only to 'cosmopolitan' SNPs. Can anyone please point me to a reference or documentation file?
Thanks in advance!
