Flowchart of the PhyQuart algorithm.

Simplified flowchart showing a) each of the three possible quartet relationships for a set of 4 sequences (q1, q2, q3), b) the site-pattern classification of observed (N) symmetric () and asymmetric () support (), c) the determination of plesiomorphic (old) split-supporting site-patterns given two different polarities of character transformation along the internal branch of each possible quartet tree, and , and d) estimation of expected convergent split-supporting site-patterns (,) supporting quartet q1 in ML split pattern estimations using branch length and model optimization on constraint topologies of the other two possible quartet relationships (q2, q3).
