Dataset corresponds to the article: "Porcine colonization of the Americas: A 60k SNP story" W. Burgos, C.A. Souza et al. For any correspondence, please address M. Perez-Enciso (miguel.perez@uab.es) Complete dataset contains 46259 SNP genotypes for 389 individuals. Info_sample.txt file contains information about location (Origin) and population (POPname) for each sample. MPE_378.* files contains genotypes for samples included for all analyses in the paper (PLINK format). MPE_389.* files also contains samples with high missing values that were used only in principal component analysis (PLINK format). The SNP_LD_pruned.dat file is a list of SNPs included after LD pruning. ADMIXTURE and PCA analyses were carried out using only those SNPs.
