The ligand, a cholesterol here, has 0 net-charge according to 'xleap'. I
am not sure if I need to work out the partial atomic charge for the
lignad. I only want to subject the system (protein and ligand) to
minimization and a short MD. So I can have rough idea on how the
cholesterol located inside the protein. In this case, how necessary to
care about the ligand charge statue?
Thank you for any advices.
All the best
Bo
