For analysis of phylogenies. Includes a wide range of randomization methods, consensus methods, tree comparison measures, and calculates reconciled trees. Now aging, and available only for Windows machines, but still has some unique features. Much of the functionality is now replaced by RadCon, GeneTree, TreeMap and the latest release of PAUP.
Uses reconciled trees to compare gene trees and species trees, explaining incongruence between the phylogenies by postulating horizontal transfer, gene duplication and loss events. Reprints of papers describing the methods are available from the GeneTree web page. Available for Macintosh and Windows.
PAUP is the most widely used package for phylogenetic inference, and now implements maximum likelihood and distance methods as well as various forms of parsimony. Powerful and very easy to use, particularly the Mac version.
