[gmx-users] using charmm rtf and parameter files in gromacs

[Sudharsan Sridharan]

Hi all,

I'm running a simulation for an antibody-drug conjugate system using CHARMm
and NAMD. I have files called .prm (parameters), molecule.rtf and
forcefield.rtf files from this run. I'd like to use these files and
information to run a simulation in gromacs for the same system (to take
advantage of speed offered and due to other technical issues). How can I
convert these to files that can be used by gromacs? Can these converted
files be supplied to gromacs commands directly? I've been reading the
gromacs manual (v4.5) but not entirely sure how to go about it.

Any tips and advice would help. Many thanks.

Kind regards,
Sid.
