   Hi Ben,
     I am very luck and pleasure to get your instant reply.As you refered in
   your first mail,van der Waals parameters of the Manganese I have obtained by
   the website http://www.pharmacy.manchester.ac.uk/bryce/amber(you may take a
   look at the attachment).Although I have obtained the parameter with MN2+,I
   don't know how to change these MN2+ parameters into metalparm.xml(like zn
   <entry mass="65.40" name="ZN" vdwRadius="1.1" potentialWellDepth="0.0125"
   element="Zn" hybridization="sp3" description="Zn(II), Merz, PAK,
   JACS,113,8262"/>) and metals.xml(like zn </fragment>
       <fragment code="METSM ZN" identity="Zinc(II) Ion" symbol=" ZN" type="m">
         <atom atNum="30" atmCharge="2.0" bond12="-1" bond13="-2" bond14="-3"
   bondAngle="90.0" bondLength="1.0" bondTorsion="180.0" chain="M"
   identity="ZN " index="1" type="ZN" symbol="Zn" kind="0"/>
         <alias alias=" ZN " original="ZN "/>
         <alias alias=" ZN" original="ZN "/>).

    I also would like to need your advises,because I encounter some new
   problems:
   (1) when I created the side chain model by hand,I dont know how to add the
   ligand with a small molecule that has three oxygen coordnated with two MN2+
   in the *_sidechain.bcl.If I dont add the ligand information in that file.
   (2) I also runed successfully MCPB -i *_sidechain.bcl -l
   *_sidechian.bcl.log.The log showed that MCPB Exited Normally,I can get the
   two files with *_sidechain_fc.com and *_sidechain_opt.com,habe these two
   files been optimised by gaussian?
                                                                     Best
   Regards
                                                                     JiYuan
