TACT: Taxonomic Addition for Complete Trees
TACT is a Python app for stochastic polytomy resolution. It uses birth-death-sampling estimators across an ultrametric phylogeny to generate branching times for unsampled taxa, using taxonomic information to compatibly place new taxa onto a backbone phylogeny.
Getting started with TACT
TACT is described more fully in its manuscript. If you use TACT, please cite:

TACT owes its existence to much foundational work in the area of stochastic polytomy resolution, namely PASTIS and CorSiM.
