Dear NAMD users,
I built a molecule in CHARMM-GUI website, in Ligand Reader & Modeler section. The molecule has a bromine atom attached to a benzene, so CHARMM builds Br with a lone pair (LP1).
Using NAMD, I had problems in choosing the right amount and combination of parameter files to start the calculations. I put all the parameters I used for the other molecules, and also some CGenFF parameters from the newest version (toppar_c36_jul20).
I tried all combinations but I receive always some problems. Does anyone know what are the right parameter files to recognise a LP attached to a halogen? And there is something (parameters, force field....) I have to change in this case?
Thank you in advance
