Pectinate Topology Results. Figure 5A shows the twelve taxa pectinate topology input into the simulation pipeline. Figure 5B shows the stacked histograms for the symmetric distances for 200 replicate correlation-based NJ. Columns 1-3 show S1 as the reference taxa, 4-6 show S6, and 7-9 represent taxon S12. Figure 5C give the stacked histogram for the symmetric distance for the Euclidean distance based NJ trees, 100 replicates. The order for reference taxa is the same as above. Figure 5D gives the corresponding stacked histogram for 100 replicate PMR trees. Two examples of this topology, six and eight steps away from the reference, are given in Figure 6B and 6C.
