REMARK nonbonded parameters according to
REMARK Loncharich, RJ, & Brooks, BR (1989), Proteins 6:32-45

nbonds
	! no 1-2, no 1-3 interaction, special 1-4 vdW, scaled 1-4 elec
	nbxmod=5 

	! pairlist and interaction cutoffs
	cutnb=10.0 ctofnb=9.0 ctonnb=5.0 tolerance=0.5

	! atom-based cutoff
	atom ! from group; atom is normally more stable

	! elec switching
	switch 

	! distance dependent dielectric
	rdiel 

	! dielectric constant
	eps=1.0 

	! scale factor for 1-4 elec
	e14fac=0.833333 ! for amber; from 0.4 for param19

	! vdW switching
	vswitch

	! below this interatomic distance a warning is issued
        wmin=1.5
