Hello everyone, I am having an issue with PyMOL's save/load command. What I am doing is that by using PDB files of RNA structures, I am doing some perturbations to the torsion angles, saving this updated structure with cmd.save(), and then using the cmd.load() command to load back my saved structure.
The issue is that although I can perturb any torsion angle as many times as I want with PyMOL after cmd.load() for the PDB file downloaded from PDB, the same is not true for the case above. Things that happen after loading a PDB file saved by PyMOL is that some torsion angles could be changed, whereas most of them keep staying the same no matter what the perturbation amount applied.
By the way, I am using cmd.get_dihedral() to read the angles, and cmd.set_dihedral() to change the angles.
Any help would be appreciated :)
