[PyMOL] Draw Ellipsoid

[Sean L. <mag...@ho...>]

Hi PyMOLers,
I am trying to use the built-in functionality to draw a user-defined ellipsoid and I am doing this by adding an extra ANISOU line in my PDB.  Here is a test case:
ATOM      2  CA  ALA D 500      -1.217   1.844  -2.065  1.00  1.00          CAANISOU    2  CA  ALA D 500    26170  51470 166480  20820 -91370 -57530      CATEREND

The upper triangle of my un-diagonalized, symmetric matrix looks like this:
26.167     2.082    -9.137                    5.147    -5.753                               16.648
I had read in the PDB format documentation that: 1) The values are given as U[1,1], U[2,2], U[3,3], U[1,2], U[1,3], U[2,3] 2) And that the values are scaled by a factor of 10**4
I've tried the "show ellipsoid" example on the PyMOL-Wiki which worked fine.  I just can't seem to get this to work.  As well, I've tried the Ellipsoid python script but the resulting CGO that it draws doesn't seem to be correct.
Any help would be greatly appreciated.
