A free, open-source desktop application for drawing and viewing phylogenetic trees, with features like easy editing of basic tree aesthetics and support for large datasets.

What is FigTree?

FigTree is a graphical viewer and tree editor program for phylogenetic trees. It is designed to be simple to use, providing basic functions for manipulating tree layout and appearance, such as changing branch widths, node shapes, colors and transparencies. FigTree supports the importing and exporting of trees in standard formats including Newick, NEXUS and phyloXML, allowing trees produced by different programs to be viewed and edited.

Some key features of FigTree include:

• Editing branch lengths, labels, supports and confidence values
• Applying line width, color, transparency settings
• Tree rotation, zooming and root placement
• Export to vector and raster graphical formats like PDF, SVG and PNG
• Support for large trees with thousands of taxa
• Rapid rendering and interactive display
• Free and open source software

As an easy-to-use and flexible phylogenetic tree viewer and graphic tool, FigTree serves as an accessory program to many popular phylogenetics packages. It allows users to visualize and tweak the final presentation of estimated evolutionary relationships without needing to redo the entire phylogenetic analysis. FigTree is written in Java and works on all major operating systems.
