Figure S1. The final assembled "guide" tree used to direct the profile alignments across Asterales. Each "terminal" represents the name of the name of the 180-alignment files output from our saturation analysis. We assembled a "guide" tree representing the relationships among the alignment files by compiling and grafting together published phylogenies. This guide tree was then traversed in a post-order manner, performing each profile-to-profile alignment working recursively back to the root.

The "guide" tree used to direct the profile alignments across green plants (Viridiplantae). Similar to Fig S1, each terminal in the tree represents a separate alignment file output from our saturation analysis. Due to the large uncertainty at several nodes, members of a polytomy were profile aligned to find the best order.
