Dear Anja,
I'm not sure why you want the orientation of the
molecule in pymol, but working out the orientation of the crystal at
phi=0 is straightforward in imosflm.
Read the image, index it and go to Strategy". In the strategy pane it
gives the angles between the a,b,c axes of the crystal and the
laboratory X,Y,Z coordinate frame. X is along the X-ray beam, Z along
the rotation axis.

Hi there,
we were taking UV/ vis spectra of a protein crystal that show
different features depending on the crystal orientation in the beam.
The question is now how to correlate the UV/ vis spectra with the
solved
structure. We know that it has a special feature at e.g. image 1
(0°). So
how can we get the orientation of the molecule in pymol so that it
corresponds to its orientation in the crystal at that exact image?
Thanks a lot,
Anja
