Hi,:
Is it possible to solvate the system using coarse grained water molecule? I tried command: genbox -cp cg_protein.pdb -cs cgwat.pdb -o cg_protein_water.pdb, but get Segmentation fault. Can anyone give me some suggestion or basic procedure to build a coarse grained system?
     Thanks in advance.
Bin

Hi, all:
Has anyone done the coarse graining using MARTINI force field? Could you give me any suggestion on how to build a coarse grained model from the AA system? I checked the website(http://md.chem.rug.nl/~marrink/MARTINI/Coordinates.html ) and it seems to me they only provide a script for coarse graining peptide. My AA system will include protein+lipid+water.
The script indeed provides only transformation from AA to CG for proteins.
It should be soon available for any AA system.
In the mean time you can do it with a script of your own, choosing the
atoms from your AA file.

   Thanks in advance.
