Copying metal and ligands to the model....

Hi

I have built homology models using DS25.For comparison purposes; I built again models using automated SWISS Model. Now I am trying to use DS25 to copy the ligand and metal Mg 2+ to the model. I don’t know how to copy these ligands and metal to the model. Would you please help me how to do that using DS25?

Thanks in advance

Kind regards,
Malai
