I have been doing similar things with Ca ions. I don't see anything you're doing that is definitely wrong, but I do do notice that in my .ali file I have not separated the Ca by a '/' .  Also make sure the knowns are where the system can access them (that would give you an error message that would probably stop execution, so probably that's not the problem). Does 1BP3 have the Zn and all its ligands properly oriented?

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
