Hi all, I used AutoSol to generate SAD phases for a protein after completing a partial MR model. My strategy worked, but I noticed there were more heavy atom sites in the solution than I was expecting. Having continued to build and refine the structure, I am fairly certain that I know which sites are the real sites and which ones are noise. I would like to use the real sites to reproduce the experimental phases in AutoSol or another Phenix module to perhaps improve the map quality (essentially running just SOLVE or Phaser without HYSS or model-building). What is the right approach? I am guessing something like this: phenix.autosol data.sca sequence.dat sites_file=sites.pdb build=False Cheers, Kyle Kyle T.
