If it's close together, just open the file in coot and use the regularize command to put them where they should be. Or, better yet, use real-space-refine to optimize it (note, this needs a map).

Chris

Subject: [phenixbb] MSE gap

Hello,

I seem to be having a problem with phenix.refine and the
seleno-methionine residue (resname MSE).

It seems that I have a gap in the peptide bond between the C atoms and
the N atom of the subsequent residue.  Is there something I could add
to the restraints_edits.params file to get it to click together?  What
is the distance_ideal and sigma for a peptide bond?

Thanks for your help,
Troy
