[gmx-users] OPLS angles

[Prasad Gajula]

Dear Gromacs users,

I am using OPLS forcefield for my simulations. The molecule also contains
di iron. It has ligand bonds with some other residues. How can I define
new
angles for it. Though I am able to define bonds, but not able to angles
and dihedral etc.
grompp generating warnings saying that using default angle zero......
could some one suggest me where to define angles?
Looking forward for any help!
Best regards
Gajula
