Using the first 32 dimensions of the Reference 3 PCA, I tried to classify the 51 South Asian populations. I did not try a full clustering on all populations because that took too long and seemed like there were more than 150 clusters.
You can see the South Asians on 3-D PCA plots of the first four principal components.
The clustering results from Mclust are in a spreadsheet.
PS. I used 32 eigenvectors as that's what gave me the maximum number of clusters with a small number of outliers.
