plane can be in any order
Chiral the order matters, see doc
CHIRAL <central atom> <atom2> <atom3> <atom4>
List of atoms in chiral group.
Note the TNT convention for chiral groups: 1st atom is central atom
Look from central atom towards the lowest-priority atom (nearly always
H), then list the other atoms (which are towards you) in a clockwise
order.

The protin dictionary file is described in the protin documentation
