Difficulty adding the martini force field was created by jcopp
Hi, I only have a few months experience with GROMACS and this is my first foray into coarse graining. However I'm struggling with adding the Martini force field to GROMACS.
Previously the only forcefield I've had to add to GROMACS was CHARM. However with that I found a folder to download that contained everything I needed such as the atomtypes.atp, ffbonded.itp, .rtp ect files, which I then added to the top folder within GROMACS.
I am unable to find any of these other files for the Martini force field in the downloads section only the input parameter.itp files as well as .itp files for aminoacids, solvents ect.
I was wondering if I was looking in the wrong place or if theirs something I need to these .itp files before the forcefield will work.
Thank you in advance.

Hi,
You can find the ITP files for the force field in the download section of the website: md.chem.rug.nl/index.php/force-field-par...particle-definitions
There are no RTP files for martini and they are not needed anyway. To use martini, you have to include the main martini itp in your top file using the "#include" statement. You can find more detailed explanations in the tutorials: md.chem.rug.nl/index.php/tutorials
