You can use phenix.ligand_linking model.pdb to get the linking files for linking the carbohydrate in refinement. You should inspect the file/s. If you have any trouble feel free to send me your model (directly). Nigel On Wed, Jul 4, 2012 at 12:28 PM, crystallogrphy wrote:

Hi,

I want to refine my structure including a sugar oligomer as the ligand in Phenix GUI.

I first put each subunit into the density and merge them together as the oligomer in Coot. Then I merged the oligomer coordinates to the protein file. Then I run phenix.elbow to get the cif file. Finally, I run phenix.refine. However, the oligomer units were pushed away from each other. I guess I need to modify the cif file to link the oligo units together. Does anyone know how I can I do it?

thanks!
