Description
Dendroscope is a computer program designed for the visualisation and interactive manipulation of phylogenetic trees and networks. It supports the display of very large trees (up to millions of leaves) and provides multiple layout options, such as rectangular, circular, and radial representations. The software enables users to explore tree topology, edit branch lengths, annotate leaves, and perform basic analyses such as rerooting or collapsing subtrees.
Development and History
The original version of Dendroscope was released in the early 2000s by a development team at the University of Tübingen, Germany. Subsequent versions have expanded functionality and improved performance; notable releases include Dendroscope 2 (introducing enhanced zooming and navigation) and Dendroscope 3 (adding support for phylogenetic networks and a modern graphical user interface). The software is written in Java, allowing it to run on major operating systems (Windows, macOS, Linux) without requiring dedicated hardware.
Key Features
| Feature | Description |
|---|---|
| Scalable visualisation | Handles trees with hundreds of thousands to millions of taxa while maintaining interactive speeds. |
| Multiple layouts | Rectangular, circular, and fan (radial) tree renderings; network visualisations for reticulate events. |
| Editing tools | Rerooting, subtree extraction, branch length modification, and leaf label editing. |
| Annotation | Supports colour‑coding, symbols, and textual notes attached to taxa or clades. |
| Export options | Saves visualisations in common image formats (PNG, SVG, PDF) and vector graphic files. |
| File compatibility | Reads and writes standard phylogenetic file formats such as Newick, Nexus, and Extended Newick for networks. |
| Scripting support | Provides a command‑line interface for batch processing and integration with pipelines. |
Availability
Dendroscope is distributed freely for academic and non‑commercial use. Executable packages and source code are hosted on the project’s website and on public code repositories. Users may download pre‑compiled binaries for their operating system or compile the Java source themselves.
