8 # DM 14 June 2006 - also calculates solvent penalty for all enabled solvent
|
|
|
9 # SOLVENT_PENALTY is defined as a fraction of the ligand binding penalty
|
|
|
10 # i.e. ligand binding penalty = 1.0 * WEIGHT
|
|
|
11 # solvent binding penalty = N(enabled solvent) * SOLVENT_PENALTY * WEIGHT
|
|
|
12 # 0.37 * 5.4 = 2.0 kJ/mol, which corresponds to GOLD Chemscore penalty
