Thank you MaryamI want to use this force field in the first step of generating the topology file (pdb2gmx command in the force field shown after this command). Is it possible? and unfortunately I don't know how to find the necessary files of this force field. I searched a lot but I didn't succeed.
I have another question, is it possible to acetylate or ammoniate a peptide with gromacs?
thank you, M.

let me modify my previous message: in the g_x2top command, not grompp :-)

Yes that's possible. You should just have the necessary files of your desired forcefield(.atp,.itp,...), and put them in a folder. in the grompp command just add -ff folder name. that's all! It will use your forcefield instead of the present forcefields in gromacs.
