There is a list of samples who are part of the project available from this spreadsheet. There is also a pedigree file available from ftp://ftp.1000genomes.ebi.ac.uk/vol1/ftp/technical/working/20130606_sample_info/20130606_g1k.ped
Please note this spreadsheet does list samples who are related to the ones we are sequencing but aren’t themselves being sequenced. If a sample has no data in the Total LC or Total E Sequence columns it means it was not sequenced for the main project
