TreeView X is program to display phylogenetic trees on Unix-like platforms. It can read and display NEXUS and Newick format tree files (such as those output by PAUP*, ClustalX, TREE-PUZZLE, and other programs). It has a subset of the functionality of the version of TreeView available for the Mac Classic and Windows (it is roughly equivalent to version 0.95 of TreeView).
