<restraints-dihedral-statement> :==
nassign=<integer>
Required parameter that specifies the maximum expected number
of assignments. This must be greater than of equal to the actual number.
cv=<integer>
Select partition number for cross-validation.
?
Print a list of current dihedral constraints.
reset
Resets the dihedral constraint list.
The functional form of the restraint is:
E = constant * well( phi - equilibrium , range )**exponent
where,
well(a,b) = a-b a > b
well(a,b) = 0 -b < a < b
well(a,b) = a+b a < -b
