Figure 4

The effect of rate heterogeneity on clustering accuracy. In each panel, the bar chart shows the ARI values (Y-axis on the left) observed from clustering of the data simulated using α values (the shape parameter) of gamma distribution set at (a) 0.5, (b) 1.0, and (c) 2.0, using (i) BLAST+MCL, (ii) UBLAST+MCL, and (iii) UCLUST, across the specific parameter settings (X-axis on each panel: I for MCL, ID for UCLUST). All numbers shown are averaged across five replicates in each instance. Standard deviation from the mean in each cases (not shown) is < 0.02. The δ values are plotted within the same panel (Y-axis on the right). See also Additional file 1: Figure S6.
