Hi MD people!
Some questions about g_lie.....
My purpose is to score different ligands and get a rough estimation of
the free energy of binding between free and bound state of the ligands
and protein of interest.
1. When I run my ligands in water without the protein, should
I add counterions (Cl and Na) to make the system neutral.
2. Should I put any restraints on the ligand in the simulation without
3. When I run my ligand bound to the protein. Should I put restraints
any restrains on protein or ligand My initial thought would be to put
on c-alpha of the protein and let the rest of the system be "free".
Thank you for any suggestions or comments, by the way I have checked all
previous threads with g_lie or lie without any to me clear suggestions
about these questions.
