CCL:Keeping coordinates fixed in g03 ONIOM calculation



Hello CCL

 

I have a problem in fixing the Cartesian coordinates in an ONIOM calculation with g03. I have used opt=(Modredundant) and I did give the correct input after the cartesian coordinates, but when I run the calculation my coordinates are changed in the MM-layer and do not stay fixed. Is it possible to fix the coordinates in g03? I would really appreciate any help. Thank you.
