Overview

ETE (Environment for Tree Exploration) is a toolkit that assists in the automated manipulation, analysis and visualization of trees. It is mainly written in Python, and includes many extra functionalities for phylogenetic trees.

Its main features include:

• Read and write support for trees in Newick format
• Multiple functions for traversing, searching and manipulating tree topologies and node annotations
• Integration with NCBI Taxonomic database
• Integration with GTDB database
• Programmatic visualization framework
• Visualization of huge trees based on adaptive zooming
• Comparing trees
• Phylogenetic functions
  • orthology detection
  • phylogenetic distance?
• Command line tools
  • phylogenetic reconstruction protocols
  • tree comparison
  • tree diff

Installation of ETE v4

To start

• Clone this repo to local computer with git clone https://github.com/etetoolkit/ete.git (or git clone git@github.com:etetoolkit/ete.git if you have the right permissions)
• Change to ete4 branch git checkout ete4
• Install dependecies
  • Cython (you can install it through Conda with mamba install cython or conda install -c conda-forge cython)
  • Additional dependencies: flask flask-cors flask-httpauth flask-restful flask-compress numpy PyQt5 (you can install them with pip install <list of dependencies>)
• Build and install ete4 from repo's root directory: pip install -e .

(In Linux there may be some cases where the gcc library must be installed, which can be done with conda install -c conda-forge gcc_linux-64)

Getting support

Rather than sending direct support-related emails to the developers, it is better to keep the communication public.

For question on how to use ETE in the bioinformatics context, use Biostars with the etetoolkit tag, or stack overflow.

For bug reports, feature requests and general discussion, use https://github.com/etetoolkit/ete/issues

For more technical problems, you can also use the official ETE mailing list at https://groups.google.com/d/forum/etetoolkit. To avoid spam, messages from new users are moderated. Expect some delay until your first message appears after your account is validated.
