Phylonium - fast and accurate estimation of evolutionary distances

This is the phylonium program for estimating the evolutionary distances between closely related genomes. It is much faster than alignment based approaches for phylogeny reconstruction and usually more accurate than competing alignment-free methods.

Dependencies, Installation and Usage

This program depends on two external libraries: libdivsufsort and the GSL. Both should be available for installation through a package manager of your choice. Furthermore, to build from the git repository the autotools are required.

Assuming all prerequisites are installed, the build can be started as follows.

$ autoreconf -fi -Im4
$ ./configure
$ make
$ make install

After a successful build the phylonium executable is found in the src directory. It can then be run as a simple command line tool. All the sequences in one FASTA file are considered to be contigs of the same genome. The filename without the extension is used as ID in the output.

$ phylonium Seq1.fasta Seq2.fasta
Seq1     0.0  0.1
Seq2     0.1  0.0

The output is a distance matrix in PHYLIP format. Use phylip neighbor, mat nj from mattools or any other neighbor-joining implementation to build the phylogenetic tree.
