[gmx-users] periodic moleules

I am trying to build a hydrogel polymeric system and I want to make
use of the option periodic_molecules.
In this regard I am a little bit confused..... are there any other
keywords except the option 'peridic molecules' that I have to set to
define a periodic polymer chain e.g. in the molecular topology file?
Because in the case I define a bond between the last atom of the
chain and the first one, how does the grompp and mdrun know that the
molecule is periodic and not cyclic?
I also suppose that the angle and dihedrals that cross the periodic
border should also be defined.
Is there a place where I can find how to define periodic molecules in Gromacs?
Thanks a lot for any suggestions,
