I am in the process of refining parameters from an SBCG
simulation of a biological protein unit (unsolvated,
unionized). When I extract the bond and angle parameters
using the iterative methods in the VMD SBCG tutorial, I
obtain .dat files with the following values for all bond
spring constants: 1.#IO
If anyone has encountered this problem and found a valid
solution, I would appreciate your input.
