Dear Cristina, In CCP4 you've got two options that use the modern approach (Acedrg):
(1) CCP4i2 -> Ligands -> Make Covalent Link. (2) Coot -> Calculate -> Modules -> CCP4. This will make a "CCP4" menu appear that contains the option: Make Link via Acedrg. Hopefully it's pretty self-explanatory from there - you'll end up with a CIF dictionary containing the link description, which you can then pass to your refinement program. Both of these options require the latest version of CCP4 (7.1).
