plot trees, edit trees, or make consensus trees

[Icon] DRAWGRAM. Plots rooted phylogenies, cladograms, circular trees and phenograms in a wide variety of user-controllable formats. The program is interactive and allows previewing of the tree on PC, Macintosh, or X Windows screens, or on Tektronix or Digital graphics terminals. Final output can be to a file formatted for one of the drawing programs, for a ray-tracing or VRML browser, or one at can be sent to a laser printer (such as Postscript or PCL-compatible printers), on graphics screens or terminals, on pen plotters or on dot matrix printers capable of graphics. Select here to see a sample plot.

[Icon] DRAWTREE. Similar to DRAWGRAM but plots unrooted phylogenies. Select here to see a sample plot.

[Icon] CONSENSE. Computes consensus trees by the majority-rule consensus tree method, which also allows one to easily find the strict consensus tree. Does NOT compute the Adams consensus tree. Trees are input in a tree file in standard nested-parenthesis notation, which is produced by many of the tree estimation programs in the package. This program can be used as the final step in doing bootstrap analyses for many of the methods in the package.

[Icon] TREEDIST. Computes the Branch Score distance between trees, which allows for differences in tree topology and which also makes use of branch lengths. Also computes the Robinson-Foulds symmetric difference distance between trees, which allows for differences in tree topology but does not use branch lengths.

[Icon] RETREE. Reads in a tree (with branch lengths if necessary) and allows you to reroot the tree, to flip branches, to change species names and branch lengths, and then write the result out. Can be used to convert between rooted and unrooted trees, and to write the tree into a preliminary version of a new XML tree file format which is under development and which is described in the RETREE documentation web page.
