Second Excel features additional statistic data:
1) Population concordance ratio (read more about this test in Dienekes' blog) - the row represents a test in which pairs of individuals from one populations were compared against individuals from the population of each column;
the column represents inividuals from same populations used as an "outgroup" for comparison against pairs of individuals from each row.
2) Mclust - using the Mclust package one can check if ADMIXTURE program correctly identify the clusters
3) K=8 for project's populations and members
