[gmx-users] Carbon Nanotube Residue

[jolander at rci.rutgers.edu]

I'm new to gromacs and the past week or so I've been digging through the
archives so that I can simulate a carbon nanotube. I've been able find
coordinates for the carbon nanotube as well as the parameters for the
force field. My question is:

Do I define the parameters in the force field file or can I do it in pdb
file?

I'm asking because I'm unable to change the force field file, so if I
could just define the carbon nano tube residue in the pdb file that would
help me out a lot.

Thanks,
