Vladimir Makarenkov and Philippe Casgrain of the Departement de Sciences
Biologiques of the Universite de Montréal have released T-REX (Tree
Reconstruction). This program performs: five methods of fitting a
phylogenetic (additive) tree to a given dissimilarity; four methods of
fitting a phylogenetic tree to a given dissimilarity containing missing
values; a method of reconstruction of a reticulation network from a given
dissimilarity (it allows the user to detect hybridization or mutation
events, or to represent reticulate evolution process). The program also
allows the user to display a few kinds of Tree Drawing (Hierarchical,
Radial and Axial) and to manipulate them interactively. Several input and
output formats have been adopted in T-REX, comprising Newick, PHYLIP and
T-REX data formats. Executables for Windows 9x/NT, Macintosh PowerMacs, and
for 32-bit DOS version are available at the T-REX web site at
