heteroatoms_zinc

Hi all, 

i'm trying to get modeller to include a zinc atom in my model. I have mastered the art ofgetting teh zinc read into the program, however the model it produces has the zinc miles away and the
coordinating residues stubbornly unligated. 

How does one go about instructing modeller to coordinate the zinc atom. I have a histine and a asp coordinating it. 

i have attached my alignment and inputfiles 

regards

Alys
