Dear Justin, Thanks for your reply. Here is the CMV.log file . Please check it.
What you've posted is output from grompp. Note that if you're trying to send attachments, the list rejects them.
Actually, the .pdb file I am using is already minimized and we are using the same file for amber 11 and Octree based molecular dynamic package.
Something doesn't add up. The energy values were indicative of a completely unphysical system.
I will also do the minimization step to see what happens. One thing I also want to mention is when I run grompp -f mdr.mdp -c conf.gro -p topol.top -o imd.tpr command, I get following the log. NOTE 1 [file mdr.mdp]: Tumbling and or flying ice-cubes: We are not removing rotation around center of mass in a non-periodic system. You should probably set comm_mode = ANGULAR.
For a single-point energy evaluation this probably isn't significant.
NOTE 2 [file mdr.mdp]: You are using a cut-off for VdW interactions with NVE, for good energy conservation use vdwtype = Shift (possibly with DispCorr) NOTE 3 [file mdr.mdp]: You are using a cut-off for electrostatics with NVE, for good energy conservation use coulombtype = PME-Switch or Reaction-Field-zero
Finite cutoffs do have a significant outcome of implicit calculations, but if you're doing this to remain consistent with other software, I suppose you have to keep them as they are.
NOTE 4 [file mdr.mdp]: No SA (non-polar) calculation requested together with GB. Are you sure this is what you want?

I just backed up imd.tpr to ./#imd.tpr.1# gcq#97: "The Universe is Somewhere In Here" (J.G.E.M. Fraaije) I was only interested in non bonded terms (Specially GB-Energy), so I guess, exclusion of bonded terms is not a problem.
How are you excluding bonded terms? If you're hacking the topology to remove the bonds, you're going to get a bunch of junk. I haven't followed this entire thread fully, but if you're trying to just get certain energies and not others, that's what mdrun -rerun is for. You don't initiate an mdrun with a broken physical model, otherwise the output will be nonsense.
