[phenixbb] ligand cif file

Hi there, Now I use phenix.elbow to produce the cif file of the ligand instead of using Prodrg. but I find a problem with this cif file, the C=N bond is not right, it becomes C-N in the cif file, so it does not fit the electron density, what should I do to modify the cif file to chage C-N to C=N ?
