Dear all,
i have a simple question regarding definition of proper & improper
dihedral type in gromacs. As in ffgmxbon.itp.....
----------------------------------------------------
[ dihedraltypes ]
; j k func phi0 cp mult
C OA 1 180.000 16.736 2
C N 1 180.000 33.472 2
[ dihedraltypes ]
; i l func q0 cq
NR5* NR5 2 0.000 167.360
NR5* NR5* 2 0.000 167.360
--------------------------------------------------------
where func=1 for proper
func=2 for improper
func=3 for R.B.
Is for proper dihedral 2nd & 3rd atom and for improper dihedral 1st & last atom
is considered?
