</div>But when I opened resolve_composite_map.mtz and *_ed.pdb in Coot, I could only see one monomer of the protein in Coot. It should be two dimers of the protein plus two pieces of DNA.

It seems that something in� *_ed.pdb file is not recognized by Coot.� I don't know whether any of you had this before and would have any suggestions for me. <br>
When I opened *_ed. pdb with text file and found out that the word "break" is used instead of "ter" between different chains, so I replaced all "break" with "ter", but this didn't help....<br>
