Figure 3From: Gene tree correction guided by orthologyThe Max Orthology problem. An instance of the max orthology problem, with X being the highest preservable descendants of the root of G in figure 2. (1) The starting tree F0, which is a copy of S. (2) The F k tree, which depicts the tree obtained after grafting every node of X. (3) The final tree F, obtained by removing the leaves initially in F0 and standardizing.Back to article page
