TreeView is a program for displaying and printing phylogenies. The program reads most NEXUS tree files (such as those produced by PAUP and COMPONENT) and PHYLIP style tree files (including those produced by fastDNAml and CLUSTALW).
The program supports drag and drop opening of files, so that if TreeView is running you can open a tree file by dragging the file (using, say, File Manager or XTree for Windows) onto the interface. It will read files that contain trees with up to 500 terminal taxa according to the developers but the number of trees is limited by the amount of memory available on your computer.
Once open, TreeView displays a single tree in the tree window. It displays the tree's name on the status bar and if it contains more than one tree, then the buttons Previous and Next enable you to browse among the trees in the file. You can also use the Choose tree command to select a tree.
For those that work with phylogenies, TreeView is one of the few programs that can really enhance the way you organise and view your files.
