Another way of doing this is to define bond and angle manually. Look here for more information and example: http://phenix-online.org/documentation/refinement.htm#anch290 Pavel. On 7/8/2008 9:00 AM, Nigel W. Moriarty wrote:

eLBOW can generate the CIF links if put LINK records in the input PDB file. Otherwise you can follow the example here.

Please contact me if you have any more trouble.

Dear all,
I have a trisaccharide in my structure, and I generate the cif file with elbow (see below). Unfortunately phenix.refine seems not recognizing the bonds C5-O1 between different units and is not keeping the chain together. As far as I could understand I should also use the keyword "apply_cif_link", but I couldn't find which syntax i should use.
Thanks for the help
Daniele
