Hello all
  I obtained a top file after running the "amb2gmx.pl" script,but I feel some errors in this top file.
The functype of the [dihedral] is 3 in this top file,but the [pairs] part aslo presence in it. And the
manual is point that "with the Ryckaert-Bellemans potential the 1-4 interactions must be excluded
from the non-bonded list." So I think this top file is incorrect?
  Could you give me some opinion?
  Force field is amber03 in gmx4.5.1,ligand is disaccharide.
Thanks !
