UrsulaThanks Nigel,All I need now is a cif file for acetyl-methionine. How do I get to this? And should the cif file be for the free amino acid or for the residue in the peptide chain?

To have the refinement link the residues you should use the parameter intra_chain=True and check the bonds in the .geo file.
Paul Emsley will likely answer that Coot question.

I am trying to include a N-terminal acetylated methionine in my model.
I replaced my methionine with a AME residue from the pdb data bank and
included a link command to connect the C from AME with the N of the
second residue. The AME is defined as HETATM. When I try to regularize
this structure in Coot it doesn't recognize that the 1. and 2. residue
should stay connected. What or how do I need to define this residue or
the connection so that I can model in Coot and refine in Phenix?
