Please CC VMD-L on correspondences so that everyone can benefit from the discussion.

You have to change the offending entry in the parameter file that you are passing into NAMDEnergy.

It appears that there is something amiss with the parameter file(s) you're passing into NAMDEnergy via the -par option. The error message suggests that one of the dihedral parameters contains a periodicity of zero (n=0). Normal values are 1, 2, 3, 4, and/or 6.

Dear NAMD/VMD user,

I am calculating nonbonded energy from amber topology file usind VMD NAMDenergy plugin.
The following error are coming
