By default, the selection made<br /> in the most recent &#039;&#039;&#039;couplings select&#039;&#039;&#039; command is used, or all scalar<br /> coupling constant restraints if no selection has been made so far.<br /> <br /> Properties that can be set:<br /> <br /> * value scalar coupling constant value<br /> * tolerance scalar coupling constant tolerance<br /> * weight relative weight of the restraint<br /> * karpluscurve Karplus curve parameters<br /> <br /> Karplus curves must be specified in the form A+B*cos(d)+C*cos(d)**2,<br /> where A, B and C are real numbers, and d denotes the value of the<br /> torsion angle formed by the two scalar coupled atoms.</div>
