[gmx-users] Using external force field with GROMACS

[Souparno Adhikary]

Hi,

I want to use the latest CHARMM36m force field which I downloaded from
MacKerell group's website. I use a common HPC system and do not have an
administrator account.

Can you give me an idea how I can add this forcefield to the pdb2gmx
options? We are using quite an old version of GROMACS- 4.5.6 (I don't know
why they are not eager to update it).

Thanks,
