[gmx-users] Problems with OPLS topology files

[Goran Krilov]

Hi,

I am trying to build a topology file for a polymer, and I am receiving
the error:

Fatal error:
[ file "pvp.top", line 2607 ]:
              Proper Dih. multiplicity can not be perturbed -8.368000! 
=0.000000

However, the line in question actually contains the first if improper  
dihedral
angles that are defined as propers under the OPLS convention.
Any ideas as to what may be wrong are greatly appreciated.

Regards,
