 Hi All,
 I am trying to do ONIOM QM/MM calculation on the active site of a DNA
 polymerase system. It has a metal ion Mg2+. I tried making the Guassian Input
 File in molUP utility of VMD- optimization.com. and submit the job. But i get
 an error message showing-
  Unrecognized atomic symbol:  M-Mg2+-2.000000(PDBName=MG,ResName=MG,ResNum=)
  Symbol not recognized in MSubst.
 Can someone help me with this? Is there anything wrong with the Mg2+ symbol?
 Also it would be highly helpful if i can get a .com file just to cross check
 and see if my file has some mistakes in the format/syntax.
 Thanks in Advance
