Dear Mark;
Thank you for your instant reply. You are right, but in my case, there is a
residue 8-OxoG (oxidized G). As you know, in all of the force fields in
Gromacs package, G,C,A and T are known. In your opinion, what should I do in
case of 8-OxoG, to obtain parameters needed for this new residue?
Thank you
B.Mehrazma
