I have taken the 22 Project participants with a membership of at least 1/4 in the "South Asian" component of the K=10 standard analysis and ran them together with the populations of the "Indian Cline" described by Reich et al. (2009), as described here.
Since some of the Project's participants have either African or East Eurasian admixture they do not fall strictly along the "Indian Cline" between West-Eurasian-like Ancestral North Indians (ANI) and indigenous South Asian Ancestral South Indians (ASI). I therefore included HapMap Yoruba and Beijing Chinese to weed out these influences and ran a K=4 analysis.
Here are the individual results:
Surprisingly, either the inclusion of the Dodecad participants and/or the African and Chinese controls has served to better flesh out the Indian Cline in the ADMIXTURE results. Below is a scatterplot of the "West Eurasian" component inferred by ADMIXTURE vs. the Ancestral North Indian (ANI) of Reich et al. (2009).
R2 =0.98 indicates that the ANI component can be inferred almost perfectly by the West Eurasian ADMIXTURE percentage.
Below are participants' individual results showing their inferred ANI and ASI components:
