Update of aims population data and test with the genogeographer admixture module

Individuals from Slovenia, Greece, Albania, and Eritrea were typed with the Precision ID Ancestry Panel and included among GenoGeographer's nine reference populations (Sub-Saharan Africa, Horn of Africa, North Africa, Middle East, Europe, South/Central Asia, East Asia, and East and West Greenland). We tested the performance of GenoGeographer with the Admixture Module on AIM profiles of 3548 individuals assumed to belong to one of the reference populations. A total of 3387 (95.5 %) profiles were assigned to one or more of the reference populations, either a single population or an admixture of two or more populations, while 161 (4.5 %) profiles were not assigned to any reference population or admixtures thereof. For 1486 AIM profiles with no reference population of origin in GenoGeographer, the rejection rate was more than 70 % for AIM profiles from North and South America and less than 20 % for those from Central, North, and Northeast Asia.
