Martinize2 and vermouth: The ultimate resolution transformation tools
Martinize2 is a rewrite of Martinize. It is aimed at producing coarse-grained structures and topologies from an atomistic structure. Martinize is primarily developed for the Martini coarse-grained force field and the Gromacs simulation engine. However the architecture of the program will allow us to support a broader range of force fields and simulation engines in the future.
Vermouth (for VERsatile, MOdular, and Universal Tranformation Helper) is the python library that powers Martinize2. It allows to describe and apply transformation on molecular structures and topologies using graph algorithms.
Martinize2 and Vermouth are under development. Bugs can occur. If you encounter an issue, please report it on https://github.com/marrink-lab/vermouth-martinize/issues. Carefully check your input and output files before using them; read the messages displayed by the program.
Martinize2 and vermouth require python 3.6 or greater. They are distributed via PyPi, and can be
installed using the
pip install vermouth
This installs the last released version. You can update an existing installation by running
pip install -U vermouth.
In some cases you may want to experiment with running the latest development version. You can install this version with
the following command:
pip install git+https://github.com/marrink-lab/vermouth-martinize.git#vermouth
Note that vermouth and Martinize2, in particular development versions, may contain bugs that cause it to produce incorrect topologies. Check the produced output carefully!
The behavior of the
pip command can vary depending of the specificity of your
python installation. See the documentation on installing a python
package to learn more.
Installing Martinize2 and vermouth with
pip adds the
martinize2 program to
the research PATH. You can see the available option of the program by running:
At the moment, martinize2 tries to reproduce the interface of the original
Martinize. You can find explanations on how to use Martinize on the Martini
tutorials; in most cases, replacing calls to
martinize.py by calls to
martinize2 should produce similar results.
The documentation of the vermouth python library will come soon.
