ETE is a python programming toolkit that assists in the automated manipulation, analysis and visualization of phylogenetic trees. It provides a wide range of tree handling options, node annotation features, programmatic access to the phylomeDB database (containing thousands of pre-calculated phylogenetic trees), and automatic orthology and paralogy detection. In addition, ETE implements an interactive tree visualization system as well as a highly customizable tree drawing engine to create PDF and SVG tree images. Note that, although ETE is mainly developed as a tool for phylogenetic analysis, it can also be used to deal with clustering trees or any other data that can be represented as a hierarchical tree.
