Hi,<br><br>I am trying to use the Phenix 1.3 software to solve a structure. After using AutoSol to generate initial phases from a MAD experiment at low resolution (5.0 A), I ran AutoBuild using the solve.mtz output file from AutoSol and a .sca file for higher resolution native data that I had collected from a second crystal. Since my target structure includes both protein and DNA, however, I ran several iterations of AutoBuild changing the parameters for building protein or DNA, including different models, playing with rebuild_in_place, etc. But now that I&#39;m ready to move into manual building and refinement, I have a ton of MTZ files from my AutoBuild runs and I don&#39;t know which one(s) I should be using for my maps to guide my model-building, and which one I should consider as &quot;the original&quot; to use in a refinement program like phenix.refine or Refmac. Can anyone help put me on the right path?<br>
