MDAnalysis_ is a Python library for the analysis of computer simulations of many-body systems at the molecular scale, spanning use cases from interactions of drugs with proteins to novel materials. It is widely used in the scientific community and is written by scientists for scientists.
It works with a wide range of popular simulation packages including Gromacs, Amber, NAMD, CHARMM, DLPoly, HooMD, LAMMPS and many others — see the lists of supported
trajectory formats and
MDAnalysis also includes widely used analysis algorithms in the
The MDAnalysis project uses an
open governance model and is fiscally sponsored by
