Each time I attempt the calculation, warning message appears ststing that No bending parameters found for atom types OS-CT-OS. Essentially, the bending parametrs are missing for the O-C-O linkage. Could anybody throw some light on this problem? On a similar vein, I have problems with an indole molecule in which the bending parameters missing are of the type CA-CN-NB.Could anybody help me? Thanks in advance, Michel
