Hi gmx users, Thanks Mark very much for all your suggestions, for your detailed explanation and your patience with me. :-) Actually, I am going to study the desorption free energy of molecule 1 from the surface of molecule 2. So first I have to carry out the absorption of molecule 1 onto surfa

was a non-problem, for such an interaction energy doesn't mean much of anything anyway, even if you calculate it with some other electrostatics model. Mark [gmx-users] Re:problem with interaction energy calculated by g_energy Qiong Zhang Tue, 09 Mar 2010 01:17:02 -0800 Hi dear Mark,

group-wise. Go read up on PME if you don't understand this. Also last time I pointed out this was a non-problem, for such an interaction energy doesn't mean much of anything anyway, even if you calculate it with some other electrostatics model. Mark [gmx-users] Re:proble

Hi dear Mark, Please ignor my last mail replied to you. I made some mistake there. Yes, you are right that I am using PME. The cutoff for the real space and reciprocal space is 1.2nm. The molecules I am simulating are carbohydrates. And I am using Glycam06 Force Field.   I tried ther

Hi dear Mark, Thanks very much for your reply. Yes, you are right that I am using PME. The molecules I am simulating are carbohydrates. And I am using Glycam06 Force Field. The interaction energy I got previously is analyzed by directly using g_energy, summing up Coul_SR and LJ_SR of two gr
