Here is a PCA plot of Italian, Balkan, and Anatolian samples, together with some reference populations. I've removed 2 Roma-admixed Romanians and 3 Northern European-admixed Armenians from the Behar et al. (2010) set.
Below are MCLUST results:
Below you can see the shape of the 7 clusters:
With increasing sample sizes, I expect the validity and distinctiveness of the various clusters to improve; as you can see, there are several samples bordering different clusters or far away from most of them.
If you write to me with your ID, I will send you your results: cluster assignment followed by the two co-ordinates, so that you can locate yourself on the plot.
