Subject: [AMBER] scee term

Hi List,

I was wondering if anybody has tried using scee=2.0 with mm-pbsa? What
if I use scee=2.0 with latest versions of amber forcefield for
negatively charged ligands?

With negative charged ligands, my experience says we get very negative
energies using mm-pbsa method, because the electrostatic term
dominates and the solvation term is smaller compared to the gas phase.
What parameter would be helpful in such a case?

I appreciate your advice.
