[phenixbb] heavy atom sites in autobuild

[Bryan W. Lepore]

i'm confused about treatment of heavy atom sites in autobuild.  couple 
questions :

1.  since heavy atom sites can be treated as single atoms, should 
phenix.autobuild simply refine the positions within a protein model? i.e. 
heavy atom sites should not need to be treated as ligands, with a .cif -- 
right?

2.  if i want autobuild to build around the heavy atom site, can i just 
use input_pdb_file=heavy.pdb?  input_lig_file_list= is not working.
