a Visualizations of QIRP as in [20], comparing QIRP calculations of two dataset partitions from [3] across the tree. Partition one represents “slower” evolving sites based on a cutoff of 0.003 subs/site per million years while partition two represents “faster” evolving sites that lie above the user defined cut off value. b QIRP heat map from [3] with probabilities of QIRP quantified across a range internode lengths for a shallow node. Each row corresponds with a user defined delimitation of site-rates (loci and a concatenated dataset in this example, though heatmaps can be modified to any user defined partitions). Shadings correspond with QIRP values. Arrows in the x and y axes respectively indicate internode or sequence length from small to large
