Thanks Justin for your reply. I was wondering then how to prepare an OH.itp file from the scartch. Can it be made using pdb2gmx? Also from some old threads I came accross that hydroxide and hydroxonium ions are species which dont obey classical dynamics. I would appreciate your thoughts on this.
I would also like to know if I make an NaOH.itp somehow and then add it to my system containing the polymer is it going to behave like a polyelectrolyte? Sorry if I am asking much.
