Details on deCODEme admixture analysis

I queried deCODE about their methodology and future plans. Here are the key points from the reply I received:
  • Admixture calculations are performed using Structure 2.2.
  • The analysis involves upwards of 18,000 "hand-picked" markers.
  • Parental populations are confirmed as HapMap samples (Utah whites, Yorubans, and Chinese/Japanese).
  • Finally: "We are working on an improved alternative ancestry analysis that will use the entire collection of SNPs to segregate individuals into ancestral clusters (e.g. Northern vs. Southern European)."

In contrast, ABD/DNAprint uses 176 SNPs.
