Aah! I would expect that the DescriptorCalculator application will not
work.

IIRC, this is because  it depends on functions in DescriptorEngine that
return classes of descriptors. This function in turn depends on the
descriptor dictionary - which is currently in a state of flux (going
from plain XML to OWL).

Egon has said he will be updating the dictionary/entry class. Once thats
done I'll update the DescriptorEngine class and then everything should
be back to normal. (I should check if its done - I haven't synced with
CVS for some time)

For now, I think the easiest way to get the descriptor functionality is
to use the descriptor GUI (the big version that has everything bundled
in it).

Of course if you want atomic descriptors, this wont help since the GUI
only does the molecular ones right now.
