Accuracy of reAdmix ancestry predictions for different mixture scenarios from European populations.

Scenario	Prior	Correct position(%)	At least one correctly predicted origin (%)	Correct populations (%)	Average distance to correct population, km
50 × 50	none	100	83	16	505
	1 pop.	100	75	31	8
	equal weights	100	81	26	251
50 × 25 × 25	none	98	80	1	572
	1 pop.	100	61	2	240
25 × 25 × 25 × 25	none	99	79	0	729
	1 pop.	100	61	0	427

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.
