[gmx-users] 45a4 force field files to nucleic acids simulations

[Guilherme Menegon Giesel]

Hello folks!!!

I'm trying make simulations with nucleic acids with GROMOS. I know that was
published the article " An improved nucleic acid parameter set for the
GROMOS force field", showing new parameters to describe nucleic acids
conformations. Such parameters was inserted in a new force field: ffG45a4.
However, I didn't find in any place the files for this new force field.

Does anyone has such files??

or

Should I complement the parameters in ffG45a3 to become DNA
simulation possible?

And therefore,

How I do it?

Thanks in advance!!!!
