Accuracy of reAdmix ancestry predictions for different mixture scenarios from European populations with error term, ϵ, to simulate variability of admixture proportions within populations.

Scenario	Error, ϵ	Correct position(%)	At least one correctly predicted origin (%)	Correct populations (%)	Average distance to correct population, km
50 × 50	0.01	99	72	6	401
	0.03	99	74	5	363
	0.05	99	73	5	386
50 × 25 × 25	0.01	99	81	0	588
	0.03	99	79	0	553
	0.05	98	79	0	557
25 × 25 × 25 × 25	0.01	99	81	0	600

	0.05	98	80	0	623

Percentage of mixed ancestral population is given in the "Scenario" column. "Correct position" is defined as a prediction within 320 km of reported location. "Correct populations" is defined as a geographically correct prediction where the method correctly discriminated between neighboring populations.
