Angle

This command will create a constraint with the angle formed by the three atoms. The central atom is where the angle is placed. The <min_angle> and <max_angle>, in degrees, specifies the range of accepted values (0 <= angle <= 180).

angle (<angleConstraint>+)

	<angleConstraint>	=	<atom> <atom> <atom> <min_angle> <max_angle>
	<atom>	=	<residue> : <atomName>

Example:

 angle
 (
   A10:O3' A11:P A11:O5' 100 130
   A11:O3' A12:P A12:O5' 100 130
 )
