You can run autosol from the GUI and select "another dataset" as "YES" on
the first page. Then you can put in the SAD and the SIR datasets, and
then on a later screen you can tell the wizard to read in the heavy-atom
sites for the SAD dataset i (or it can find them again). Then it will use
the sites from the sad dataset to find the sites for the sir dataset.
You can also do this from a script...the best example that is close to
your case is $PHENIX/phenix/phenix/wizard_scripts/AutoSol.mir . You can
then add to the lines where you are reading in the SAD data something
ha_sites_file sites.xyz # the file with heavy-atom sites
However I am not sure that this is going to solve the problem because if
your map is uninterpretable from the SAD dataset ...then the difference
Fouriers for the SIR dataset may be uninterpretable too...
