Result of running Jackknife Environment Clusters with Number of sequences to keep set to 12 and Number of Permutations set to 100. The environment abbreviations are the same as described for Fig. 2. Each node is colored by the fraction of times it was recovered in the jackknife replicates. Nodes recovered >99.9% of the time are red, 90–99.9% are yellow, 70–90% are green, 50–70% are blue, and < 50% are grey. The fraction can also be viewed in the interface by moving the pointer over the colored bar.
