WebNov 6, 2024 · IQ-TREE finds parsimonious tree twice, by default: 1. to create an initial tree, and 2. to populate an initial tree set. (1) can be modified with “-t” and (2) with “-ninit 2”. Fortunately the authors recently added an option “-t PARS” to use their own algorithm for initial parsimony tree, much faster (not documented?). WebFirst, arbitrary discrete characters may have any number of states (beyond the four associated with DNA sequence data). Second, characters are typically analyzed independently rather than combining long sets of characters and assuming that they share the same model of change.
