[Chimera-users] Amber Force Field

Hi: I have noticed that scripts can start with: import MMTK import MMTK.ForceFields from MMTK.ForceFields import Amber94ForceField We are doing some side chain packing studies that would benefit from the availablity of "easy" force field calculations. Currently, the algorithm works with useRotamers() to set two neighbouring rotamers and this is followed by a simple energy calculation to evaluate the interaction energy between the two rotamers. Right now, the energy calculation is only a bit more sophisticated than a steric collision detector. Question: Can we use some functions in the MMTK.ForceFields module to get an improved energy calculation? Any suggestions would be appreciated. Cheers, Forbes
