TreeView is a program to view phylogenetic trees in your computer. A phylogenetic tree is a graphical representation of a hypothesis about the evolution of a species, with branches that separate, hybridize, or become terminated by extinction.
TreeView can read and display some of the most used tree file formats, such as NEXUS, PHYLIP, Hennig86, NONA, MEGA, and ClustalW/X. Once loaded in the application, you can choose to view the tree as a Radial Tree, a Cladogram (or a Rectangular Cladogram) or a Phylogram. You can edit the trees using the built-in Tree Editor, which will let you move, collapse or expand branches, reroot trees, rotate or swap descendants, and apply labels.
You can export any loaded tree to the NEXUS, PHYLIP, or Hennig86 formats, as well as a graphic file, in either .EMF or .WMF format. You can also print any tree. The program supports TrueType and Postscript fonts. It is possible to print multiple trees in a single page and one tree over more than one page.
