MDAnalysis is an object-oriented python toolkit to analyze molecular dynamics trajectories generated by CHARMM, Gromacs, NAMD, LAMMPS, Amber and other simulation packages.
MDAnalysis 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. In addition, atom selection commands are implemented. Trajectories can also be manipulated (for instance, fit to a reference structure) and written out.
A typical usage pattern is to iterate through a trajectory and analyze coordinates for every frame.

The published papers on MDAnalysis contain high-level descriptions of the structures and philosophy of the library together with examples of its use.

MDAnalysis was originally inspired by the Schulten Group's MDTools for Python, and the DCD reading code is derived from VMD's catdcd. MDAnalysis is GPL licensed, except for some 3rd party code that is included under GPL-compatible licenses; for instance the dcd reading code is under the UIUC Open Source Licence.

Some time-critical routines are written in C or cython and require a working C compiler. The minimum required version of Python is 3.9. MDAnalysis has been successfully used on Linux, Mac OS X and Windows.
