This was something I wanted to explore in more detail, so I naturally decided to poke around the <a href=\"http:\/\/www.genomeweb.com\/arrays\/hugo-pan-asian-snp-consortium-maps-genetic-diversity-asia\">Pan-Asian SNP<\/a> data set. The aims are  made somewhat more difficult by the fact that there are only ~56,000 markers in the data set (as opposed to ~600,000 in the HGDP and more than 1 million in the HapMap). Additionally, the intersection with other data sets is small. For example, only ~20,000 SNPs with the HGDP. With all that in mind I hazarded that something is better than nothing.  Relatives and HapMap populations were removed from the data set (thanks <a href=\"http:\/\/www.harappadna.org\/\">Zack<\/a>). Additionally, I beefed up the South Asian populations with the Gujaratis from the HapMap,which had an intersection of ~32,000 SNPs. After a few test runs I decided to remove the <a href=\"http:\/\/en.wikipedia.org\/wiki\/Mlabri_language\">Mlabri<\/a>. They always shook out very early as a separate population from many others nearby, and, their genetic distances were very high.
