[phenixbb] Refining anomalous groups

[Felix Frolow]

Hi Nath,
Happy 2013!
Is it possible to use anomalous automatism also under GUI?
Will be the event of refinement of anomalous dispersion parameters f' and f" recorded in PDB file?

Usually I check the box for "Anomalous groups", then select "Modify selections for: Anomalous groups" which brings up a screen for atom selection and definition of f' and f''.  In the past, clicking on the View/pick button launches Coot for selection of the atoms.  Sadly, now clicking on the View/pick doesn't launch Coot and instead crashes Phenix.
