gmx-top4py 0.1.3

A Python library to parse GROMACS topology files and alter associated force fields parameters.

gmx-top4py

GROMACS topology files for python

Description

The gmx-top4py project provides a python interface to

• read and write toplogy and force field information from GROMACS-type top-files
• alter force field parameters

The gmx-top4py project derives this functionality from the kimmdy project, originally developed by the graeter-group, and includes only minor modifications to parts of the original code to operate independently. The kimmdy project is licensed under the GNU General Public License v3.0 and, as a derivative work, the gmx-top4py project is distributed under the same license. See LICENSE for details.

Tutorials

The following tutorials are avaiable as Google Colab notebooks and hence do not require a local installation:

• Basic tutorial - Basic accessing of topology information with gmx-top4py
• Advanced tutorial - Advanded accessing of topology information with gmx-top4py
• Force field parameter tutorial - Adapting force field parameters with gmx-top4py
