[Chimera-users] Help in executing python script in per-frame analysis

Hi I am analysing a protein molecule (MD simulations). I wrote a python script to calculate inertia for the protein and ran it over 40000 frames. I got a data in log file but it is creating a ellipsoid around the molecule. I want 3 axes of the ellipsoid to be shown in that protein molecule not the ellipsoid as it covers the whole protein molecule. So that I can easily visualize the movement of all 3 axes of ellipsoid over the 40000 frames (means how the axes are changing during trajectory run).
