Dear VMD users:

I have a psf file generated by the charmm-gui web made with XPLOR and I
have another psf file for the same system made with the autopsf gen from
VMD both made with the same topology file. The system contains a protein +
POPC + water + ions and there is a difference in the number of angles and
dihedral b/w both psf files. I found on the namd tutorial that the psf
files generated by xplor contain more or duplicated dihedrals. Could that
be the reason for my discrepancy?
