These graphs show the estimated population structure (plotted using *distruct*) for 10 runs of
*structure* using 1056 individuals from 52 human populations.
Each graph represents the output of one run of *structure*. In
each graph, each individual is represented by a vertical line, which
is partitioned into 5 colors that represent its estimated membership
fractions in *K*=5 clusters. Black vertical lines separate the
individuals from different populations. The 10 runs shown are the 10
runs with *K*=5 that are described in Figure 1 of *Science* 298: 2381-2385
(2002).

In the pre-*CLUMPP* figure, the *distruct* plots are made directly
from the *structure* output. In the post-*CLUMPP* figure, *CLUMPP* has been used to permute the 10
runs so that the clusters align across runs. To make the figure, the
*Greedy* algorithm of *CLUMPP*
was used with 10,000 random input orders of runs. The plot shown
represents the optimal alignment among the 10,000 input orders tested.
