Dear PyMol Users,

We're using Pymol to automatically extract all the backbone dihedrals
from a protein.

I've noticed that it's very slow doing those calculations. Normally in
Fortran it will take some seconds, while in pymol it takes five minutes
or even more.

The command we issue is :

$> /opt/soft/pymol/pymol -qc dihedral.py

That dihedral.py script only reads some pdb's and and uses the function
get_dihedral()

Does anybody know why is it running so slow ? And if so, is it possible
to speed it up in any way ?

Thanks

Best Regards,
David McGiven.
