Values following underscores after the gene name indicate first, second, or third codon positions. Subset sites correspond to the order of genes in the concatenated alignment. Peak of the PI profiles are indicated in millions of years. Slope values correspond to the slope of a chord joining the peak of profile and the midpoint of the profile between the peak and the root of the tree. Bolded partitions indicate partitions removed for subsequent analysis.
