An object-oriented toolkit to analyze molecular dynamics trajectories generated by CHARMM, Gromacs, NAMD, LAMMPS, or Amber.
MDAnalysis is an object-oriented python toolkit to analyze molecular dynamics trajectories generated by CHARMM, Gromacs, Amber, NAMD, or LAMMPS; it also reads other formats (e.g. PDB files and XYZ format trajectories; see the Table of Supported Coordinate Formats for details). 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.
easy_install -U MDAnalysis pip install --upgrade MDAnalysis
In order to run the Unit Tests it is also necessary to install a separate package MDAnalysisTests containing the test and test data. As it contains about 18 MB of molecular dynamics trajectories and simulation system structures it is not included with the library itself.
