Heat map representing the “flow” of clades between phylogenetic inference strategies. We use clade flow to measure the proportion of clades inferred by one strategy that were not inferred by a different strategy. Phylogenetic inference strategies are ordered using the dendrogram. The cell at row i and column j represents the fraction of clades inferred by strategy i that were not inferred by strategy j. By definition, the heat map is asymmetric. Darker colors indicate lower levels of “flow” from a row to a column.
