MDAnalysis is a Python toolkit to analyze molecular dynamics trajectories generated by CHARMM, Amber, NAMD, LAMMPS, or Gromacs.
The test files change less frequently, take up around 70 MB of space, and are not needed for daily use of MDAnalysis so they are distributed separately from the main package.
For installation instruction please have a look at INSTALL and the instructions online at https://github.com/MDAnalysis/mdanalysis/wiki/INSTALL
The tests are described at https://github.com/MDAnalysis/mdanalysis/wiki/UnitTests
For further information please see the documentation for MDAnalysis itself.
