Hi,<br><br>I'm refining a 2.88 resolution structure and would like to pick waters. I assume the default low_resolution is set to 2.8 Angstroms and so my lower resolution map is not yielding any waters. How do I change the resolution cutoff for water picking to be 3.0 Angstroms? I tried adding "refinement.ordered_solvent.low_resolution=3.0" to my command line arguments and phenix is reading this, but the refinement crashes about 15 seconds in with the message: <br>
<br><div style="margin-left: 40px;"><br>================== Extract refinement strategy and selections =================<br><br>Sorry: Selection string 'water' results in empty selection (selects no atoms).<br></div>
<br>Thanks for your help!<br><br>-Sam<br>
