SPR Supertrees version history

1.2.1

• Bugfix release
• fixed crash bug that affected some systems/configurations

1.2.0

• Faster SPR distance calculations
• LGT analysis options
• Outgroup rooting
• Bipartition Clustering quickly ignores many SPR permutations
• Option to break SPR distance ties with the RF distance

1.1.1

• Bugfix release
• Fixed a coding error that occasionally computed one more than the SPR distance between two trees

1.1.0

• Trees can be multifurcating with -allow_multi option
• Much faster SPR distance calculations
• Many new options including collapsing unsupported bipartitions, fast consideration of unrooted trees with -simple_unrooted option, starting from a specified tree with -initial_tree option, limiting the radius of considered SPR permutations with -r option (-r 1 uses NNI permutations)

1.0.0

• initial program version.
• Computes rooted supertrees that minimize the rooted SPR distance using exact calculations or varying levels of approximation.
• Optionally computes rooted supertrees that minimize the SPR distance to any rooting of a list of unrooted input trees.
• Version used in "Subtree Prune-and-Regraft Supertrees."
