MDAnalysis is a Python library for analyzing molecular dynamics (MD) simulations. This page will guide you through quickly installing MDAnalysis, exploring a basic example, and accessing learning resources to get started.
Our Installation Quick Start guide contains instructions to get MDAnalysis up and running in a few minutes. Try this guide first.
For a more thorough installation with advanced options, including dependencies and environment configurations, see the installation instructions in the User Guide.
Once MDAnalysis is installed, you can load a trajectory and perform a simple analysis. A typical usage pattern is to iterate through a trajectory and analyze coordinates for every frame.
In the following example, the end-to-end distance of a protein and the radius of gyration of the backbone atoms are calculated:
