[phenixbb] Error when specifying anomalous scatterers in autosol.

Hi Francis,
Thanks! I think the problem is here in your cif_def_file_list
parameter file:
anomalous_scatterers {
group {
selection = "name I"
f_prime = -0.5783
f_double_prime = 6.8299
}
}
where you are specifying the name I for anomalous scatterers...which
seems perfectly reasonable, but....
unlike what you might expect, the anomalously-scattering atoms are not
added to the PDB file created by AutoSol, so the I atom is not present
during refinement and you get the error you show.
In AutoBuild, this should be added automatically, and if not, you can
add it with
input_lig_file_list=my_ha_file.pdb
So yes, just go on to AutoBuild. The build in AutoSol is really just
to see if everything is working ok...not to do a real build. The
default now is to use "helices_strands_only" so that this build goes
very fast.
I hope that helps!
