StarBEAST2 is a new method for multispecies coalescent inference of species trees and other phylogenetic parameters. It is more than 10 times faster than *BEAST, the method it replaces. It also introduces species tree relaxed clocks, which apply a separate substitution rate to each branch of the species tree. This enables accurate estimates of between-species molecular clock rates.
Before running StarBEAST2, it is a good idea to complete the latest tutorial. The tutorial covers setting up and analysing the results of different kinds of StarBEAST2 analyses using an example data set.
