Hi Arun, I am able to run your script (run ELM_ellipsoid.py) in PyMOL without reported errors or warnings, and it displays an ellipsoid centered on the hardwired position in the script. It looks like you need to edit the script to supply the center of mass of your structure, the lengths of the semi-axes and the orientation of the ellipsoid via three Eulerian angles.
Please be more explicit about what is the "intended" result. Do you really want the geodesic surfaces in Diffusion_Geometry.png? The result in ROTDIFF_Ellipsoid looks better. You can tweak the parameter settings in makeEllipsoid() to make the triangles smaller so that the surface is smoother.

And ROTDIF software provides the desired output pymol script to generate the predicted shape model information. However, it seems that I am missing some further inputs or Pymol commands for the correct initialization of the script (attached pic). As, I am not getting the intended results with the script. Can anyone please suggest the correct modifications to the attached script.... Thanks!!!
