I am trying to run a simulation on the L chain of the protein 1CPC (that is the pdb code).  I "think" I have set everything up correctly, however, when I run the simulation there are some things that I am a bit concerned about:
1) I get a warning : Warning: Not all atoms have unique coordinates. (see second line of output below).  This warning appears at each step in the console when the energies are outputted.
2) When I start the minimization process the energies values show up as 99999999.9999 (see output below).  I believe this is because of the warning above.
TCL: Minimizing for 500 steps
Warning: Not all atoms have unique coordinates.

So my question is why I am getting those warnings (that not all the atoms have unique coordinates?) This is obviously wrong but I wonder where I went wrong?  Would it have been when I generated the PSF structure?  Maybe my config file is wrong? I'm not really sure where to start to figure out what is wrong...
I have attached my config file.
thanks for any insight.
