FigTree

FigTree is a program for viewing and editing phylogenetic trees that can generate clear, “publication-ready” images from these trees.

What FigTree Is Used For

FigTree serves as a graphical interface where you can open files containing phylogenetic trees (e.g., from programs such as BEAST), view the tree, and customize its appearance. It is primarily intended for biology, evolution, and epidemiology, where researchers often work with phylogenetic trees of species or viruses.

Key Features

The program allows you to change the tree layout, colors, node shapes, and labels so that the resulting image looks good in publications or presentations. It also allows you to export to common graphic formats (e.g., PDF, SVG, PNG, JPEG) and work with annotations and attributes of branches and nodes
