A primitive Python wrapper around the Gromacs tools. The library is tested with GROMACS 4.6.5, 2018.x, 2019.x, 2020.x, and 2021.x (and 5.x and 2016.x should also work). It supports Python 2.7 and 3.6--3.9 on Linux and macOS.
GromacsWrapper also provides a small library (cook book) of often-used recipes and helper functions to set up MD simulations.
The source code is available in the GromacsWrapper git repository.
Please be aware that this is beta software that most definitely contains bugs. It is your responsibility to ensure that you are running simulations with sensible parameters.
Given a PDB file
1iee.pdb, set up and run a simple simulation (assuming
you have all other input files at hand such as the MDP files):
>>> import gromacs >>> print(gromacs.release) 2018.2 >>> help(gromacs.pdb2gmx) DESCRIPTION gmx pdb2gmx reads a .pdb (or .gro) file, reads some database files, adds hydrogens to the molecules and generates coordinates in GROMACS ... ...
