Dear Gustavo,

Thank you so much for your answer.

As I have no experience in generating parameters, would you please point out to me a way/tutorial that I could follow to generate such dispersion parameters for Mg2+ ion? I wonder if such a thing could be achieved with antechamber..

Thank you anyway for your time,

Sincerely,

Ruth
