Phylo.io web interface in “compare” mode. (A) Two large trees with the same 737 leaves but different topologies in compare mode. The yellow to blue color scheme indicates the similarity of best matching subtrees between the two trees. In the left tree, an inner node (highlighted in red) is selected, thereby highlighting its subtree (in green) and corresponding parts in the right tree (in green). (B) The same tree with the same highlighted inner node, but after automatically re-rooting and reordering subtrees.
