A program for supertree construction

The program is intended for building of the phylogenetic supertree that agrees with a set of known trees as good as possible. In particular, given a set of gene trees, the program builds the tree of species those genes are from. The program implements an original algorithm with a number of enhancements such as parallelization for use on a multiprocessor system supporting MPI (version 1.2 or above). It is noteworthy that the program supports nonbinary (polytomous) source trees.

The Super3GL program is written in C++ and has a command line interface. The code is portable and can be compiled for Windows 32/64-bit, Linux, Unix, MacOS operating systems.

The Basis3GL program implements an alternative algorithm for basis trees building in the case of ill-conditioned input data. This algorithm is significantly slower than the one included in Super3GL so it is recommended to run in parallel on a cluster. The program is also written in C++ and has a command line interface.

The basis trees obtained by Basis3GL then may be used to build a supertree with Super3GL and/or Embed3GL programs.
