[gmx-users] CMAP in Gromacs Vs. CHARMM

I'm trying to figure out the differences between Gromacs and CHARMM implementation of CMAP.
In Gromacs it seems to be defined as a 5 body term, whereas in CHARMM, its a 8 body term.
I thought CMAP was a correction between a pair of dihedrals, 4 atoms define a dihedral, so I'm not sure how the .top format can specify this relationship using only 5 atoms.
Could anyone shed some light on converting between them.
