I was also engaged in dealing with the problem about the course grain model . I find that in this CG force field , the potential functions almost don't correspond to that in the gromacs.
Hence, I wonder whether you know to how to define these new potential functions.
Thank you in advance.

Subject: [gmx-users] How can I generate a Input *.gro file of coarse grain model?
Dear all gromacs users:
I am trying to use the MARTINI CG force field from Marrink et al. in my simulation.
But I don't konw how to generate the input *.gro files.
When I use all-atom model, in gromacs I can use "genbox" "editconf" et al to generate
the input *.gro files. For example, I can use "genbox -cs -box 10 10 10 -o waterbox.gro"
to generate pure water box. But if I only have the files downloaded from
"http://md.chem.rug.nl/~marrink/MARTINI/Parameters.html" , and I use a *.top file
[ system ]
[ molecules ]
Can I generate a *.gro file according to this topology file using Gromacs' tools?
If can, how do it?
Appreciate any help in advance!
