Table 1:
Admixture proportions inferred by Treemix for 1 (M1), 3 (M3), 5 (M5), or 8 (M8) simulated migration edges (rows)

| 13 → 5 | 0.30 (0.0011) | 0.30 (0.00062) | 0.32 (0.0016) | 0.29 (0.0036) |

The direction of the simulated migration is reported in the first column (source → sink). The standard deviation from 10 iterations is shown within parentheses.
a
Treemix incorrectly inferred the migration edge 11 → 4 rather than 6 → 3 for all 10 iterations.
b
Treemix correctly inferred the 6 → 3 migration edge in 9/10 iterations, but one iteration incorrectly reported a 15 → 10 edge.
c
In 9/10 iterations, Treemix reported the source of this migration edge to be the common ancestor of 19 and 20, or 19/20 → 10.
