MDAnalysis documentation¶
| Release: | 1.1.1 |
|---|---|
| Date: | May 06, 2021 |
MDAnalysis (www.mdanalysis.org) is an object-oriented python toolkit to analyze molecular dynamics trajectories generated by CHARMM, Gromacs, Amber, NAMD, LAMMPS, DL_POLY and other packages; it also reads other formats (e.g., PDB files and XYZ format trajectories; see Table of supported coordinate formats and Table of Supported Topology Formats for the full lists). It can write most of these formats, too, together with atom selections for use in Gromacs, CHARMM, VMD and PyMol (see Selection exporters).
It allows one to read molecular dynamics trajectories and access the atomic coordinates through NumPy arrays. This provides a flexible and relatively fast framework for complex analysis tasks. Fairly complete atom Selection commands are implemented. Trajectories can also be manipulated (for instance, fit to a reference structure) and written out in a range of formats.

Installing MDAnalysis¶
The easiest approach to install the latest release is to use a package that can be installed either with pip or conda.
pip¶
Installation with pip and a minimal set of dependencies:
pip install --upgrade MDAnalysis
To install with a full set of dependencies (which includes everything needed
for MDAnalysis.analysis), add the [analysis] tag:
pip install --upgrade MDAnalysis[analysis]
conda¶
First installation with conda:
conda config --add channels conda-forge
conda install mdanalysis
which will automatically install a full set of dependencies.
To upgrade later:
conda update mdanalysis
Tests¶
If you want to run the tests or use example files to follow some of the
examples in the documentation or the tutorials, also install the
MDAnalysisTests package:
pip install --upgrade MDAnalysisTests # with pip
conda install mdanalysistests # with conda
Source Code¶
