These are the data used in "Worldwide Patterns of Ancestry, Divergence, and Admixture in Domesticated Cattle" by Decker et al., arXiv:1309.5118 ww_cattle_dryad_20Sept2013.ped contains the genotype data in PLINK PED format. Illumina A alleles are coded as 1, and Illumina B alleles are coded as 2. SNPs were filtered based on a call rate of 0.9 (--geno 0.1 command in PLINK) and a MAF of 0.0005 to remove monomorphic SNPs (--maf 0.0005). SNPs on unassigned contigs and chromosome X were removed, except for one pseudoautosomal SNP. ww_cattle_dryad_20Sept2013.map contains SNP information in PLINK PED format. Chromosome coordinates are according UMD3.1 assembly. ww_cattle_dryad_20Sept2013.pedind contains population information for 1,543 animals. Breed code descriptions can be found in Table S1 of the manuscript. Please contact Jared Decker DeckerJE@missouri.edu if you have questions.
