Haddock with metalloproteins

Hi Professor Bonvin,

Thank you so much for the great talk and tutorial on monday. I want to do some protein-DNA docking with a zinc finger protein transcription factor I work with, is there a way to add bond parameters from another force field (i use amber’s zinc amber forcefield, ZAFF) parameters for coordination bonds to the structural zinc ion? or is there already a method for HADDOCK for zinc proteins?
