FigTree

When writing a research paper on complex topics like Genetics or Evolution, everyone desires to create high-resolution visuals. FigTree makes this easy by providing plenty of tools to its users. It is a free Java-based application by Andrew Rambaut that enables you to view graphical representations of phylogenetic trees, and it was designed in particular for trees produced by BEAST. To make your work more presentable, this application offers multiple customization and annotation options so you can create ready-to-publish figures.

FigTree has a simple design with a large tree preview area and a side panel of display options. To create a figure, start by opening the main window of the software on your screen. Build your tree in a phylogenetic tool like BEAST or MEGA and save it in NEXUS or Newick format. Then, click "Open" and load the tree file into the tool. Using mouse movements, you can get information about branch lengths and node values of a particular node. From the side panel and the menu bar, you can access different customization options and create a perfect phylogenetic tree.

Features:

• A quick and easy tool to view and modify phylogenetic trees interactively.
• It displays annotations stored in the tree file, such as node support values or ages, and features a graphical user interface to view various phylogenetic illustrations.
• You can modify various components of the tree, such as scale axis, position, or node labels. It allows you to align tip labels or change their appearance.
• High-resolution figures of the phylogenetic tree can be produced, so you can use them for professional work submission or publication.
• It is written in Java and runs on Windows, macOS and Linux; version 1.4.4 fixed problems with running under Java 9 and later.
• The created figures can be exported in printable PDF or EPS format, as SVG vector graphics, or as PNG and JPEG images.

FigTree produces publication-ready figures by allowing you to create visually appealing and interactive phylogenetic trees.

What's best? FigTree is designed to be a highly valuable tool for researchers and field workers. It lets you reroot, rotate and collapse parts of the tree and customize the look of your diagrams. Install it on your Windows, macOS, or Linux computer to create clear phylogenetic tree figures. Its author now points users to PearTree as the successor of FigTree.
