      <br>
      thanks for the file - I will have a closer look. Did you mean the
      restraint did not work or it worked but you wanted something else?
      (I'm just trying to understand if this is a Phenix problem that we
      need to fix).<br>

              <div>Hi Alex,<br>
                <br>
                Nigel is the best person to reply, so he may provide
                more comments. My understanding is that
                phenix.metal_coordination command (or whatever the
                equivalent click in the GUI is) should account for
                symmetry related atoms. If not you can fix it manually.
                First create edits file using phenix.metal_coordination
                and then add&nbsp; symmetry related bonds as described here:<br>
                <br>
                <a moz-do-not-send="true"

                  target="_blank">http://www.phenix-online.org/documentation/refinement.htm#anch353</a><br>
                <br>
                Also, could you please send me the PDB file or its
                portion containing relevant to your question atoms and I
                will have a closer look?<br>
