multi ligand docking using rosetta script

  Hi all.

  I'm trying to dock  my ligand with HEM to CYP using rosetta script with XML protocol

  overall running process seems to complete without any problem, and rosetta script seems to recognize HEM and  ligand as separate entity

  But in some conformer generated by rosetta-script, there is severe clash between HEM and ligand.

  For this kind of conformer, rosetta total_score was extremely high and I could filter out this kind of unfavorable structure based on rosetta score

  But, Can I set the xml protocol to exclude these kind of conformer generation using rosetta script ?

  In xml specification manual and the paper 'RosettaLigand docking with flexible XML protocols',  there are many option and specification, but I couldn't  find

  the information related to reducing the clash between ligand.

  Attcached files are

  1. structural image which show severe clash between HEM and ligand

   2. my protocol xml file used for rosetta script

  Any kind of suggestion would be welcomed
