About MDAnalysis



MDAnalysis is developed and maintained as a freely available, open-source project by a global community of scientists. The MDAnalysis community adheres to our Code of Conduct and invites everyone to participate — be it on the mailing lists, through issue reports, or code contributions.

All contributors to the MDAnalysis library and its subprojects are acknowledged in a file called AUTHORS in each source code repository and in the list of contributions; as examples see the AUTHORS file for mdanalysis and the contributors for MDAnalysis/mdanalysis.

MDAnalysis and the algorithms implemented in the library and the subprojects are scientific software that are described in academic publications.

MDAnalysis is used in a variety of other molecular dynamics tools.

Open source

All our code and our teaching materials are available under open source licenses from repositories at https://github.com/MDAnalysis/. The MDAnalysis library itself is published under the GNU General Public License, version 2; other supporting libraries are published under the MIT or the BSD-3 clause licence.

Installable packages are available through the popular pip and conda package managers as well as some Linux distributions.


Project leadership is provided by a subset of contributors, the MDAnalysis Core Developers (@MDAnalysis/coredevs) who have produced substantial contributions over extended lengths of time and who remain active in reviewing issues and discussions on the various mailing lists. MDAnalysis Core Developers are granted commit rights (write access) to the GitHub source code repository.

MDAnalysis Core Developers

The current @MDAnalysis/coredevs team (“MDAnalysis Core Developers”) consists of:

Decision Making Process

  1. All decisions are made by simple majority1 of the MDAnalysis Core Developers.
  2. New MDAnalysis Core Developers are elected with a simple majority of current MDAnalysis Core Developers.

Code of Conduct

Everyone in the MDAnalysis community adheres to our Code of Conduct. A rotating subset of three MDAnalysis Core Developers is tasked to respond to and to investigate Code of Conduct violations.

  1. A simple majority is defined as more than half the votes cast. Abstentions or blanks are excluded in calculating a majority vote. Totals do not include votes cast by someone not entitled to vote2 or improper multiple votes by a single member. Illegal votes3 are counted as votes cast;
    if only two choices (such as a binary “yes”/”no” vote) are possible, a majority vote is more “yes” than “no” votes. 

  2. See MDAnalysis Core Developers for the list of individuals entitled to vote

  3. Illegal votes are votes that were cast for ineligible choices.
