SplitsTree4 is the leading application for computing evolutionary networks from molecular sequence data. Given an alignment of sequences, a distance matrix or a set of trees, the program will compute a phylogenetic tree or network using methods such as split decomposition, neighbor-net, consensus network, super networks methods or methods for computing hybridization or simple recombination networks.
SplitsTree4 is an all-new implementation of the SplitsTree software written in Java. Superficially, this new program is similar to previous versions of this software. However, there are substantial differences. The new program has many new features, see the manual for details.
