Dear all,
I am trying to calculate potentials for RNA structures with a serial of
tabulated potentials (non-bonded).
And the only potential I am going to use is the tabulated potentials,
and the effect from force field should be removed.
However, when I use pdb2gmx to build the topology file, I have to choose
a force field. What should I do for that? Thanks.
It sounds like you need to be constructing your own force field, completely,
from scratch. If you're not looking to use the existing force fields, this
sounds like the only real solution. You can take the time to make .xvg files
for bonded and nonbonded interactions (see the manual), but that is probably
just as much work and your simulations will be much slower.
