<div dir="ltr">Dear All Phenix Users,<div><br></div><div>Is there a way to fix certain atoms position during refinement?</div><div><br></div><div>I have some heavy atoms identified with MR-SAD, but when I build the whole molecule and have phenix to refine its position, the heavy atom's position is shifted from the anomalous signal. Therefore I would like to have these heavy atoms positions fixed during refinement. </div><div><br></div><div>Thanks!</div><div><br></div><div>Charles </div><div><div><br></div>-- <br><div class="gmail_signature">
