Dear All,
 
I just did a Phenix refine, but it gave the following sorry message:
 
Number of atoms with unknown nonbounded energy type symbol: 3.
 
I remember when I process the peptide with Coot, several H atoms were separated from the atoms they were attached to. I do not know whether this is the reason why the Phenix gives symbol 3.
 
I am looking forward to getting your reply.
 
Cheers,
