  1. Mutations are classified and counted according to their qualitative properties. Row categories separate perfectly defined mutations from those that involve ambiguous positions of some sort; "ungapped" unambiguous substitutions (mutations that do not involve gaps, i.e., indels) are given a separate category as well (Total = Ambiguous + Unambiguous, Unambiguous ≥ Ungapped). Columns relate mutations with alignment conservation information (95% threshold) and evolutionary history from the root of the tree to several types of significant events (Total = Conserved + Back-mutation - Conserved B-M + Remaining).
