[COOT] Problem with Extension- Phosphorylate this Residue

Hello all, this is my first post and I apologize if there is redundancy, but from previous searches of the archives on this board, I did not find an issue similar to mine. I am attempting to phosphorylate a threonine residue, however, I get this error: monomer-molecule-from-3-let-code TPO )

Re: [COOT] To mutate non-standard nucleic acids

Briefly, this is not the way that Coot wants you to do it. Coot wants you to Replace Residue (under modelling). Make sure that your restraints for the modified residue have the group DNA (or RNA), not monomer. Paul. From: Mailing list for users of COOT
