<p>1 revision</p> <p><b>New page</b></p><div><br /> Synopsis: dmean(&#039;&#039;integer&#039;&#039;) = &#039;&#039;real&#039;&#039;<br /> <br /> This function returns the average value (in degrees) of the torsion<br /> angle with index &#039;&#039;integer&#039;&#039; in the selected structures. The periodicity<br /> of the torsion angle is considered when calculating the average<br /> value. The average value is given by the argument of the complex<br /> number exp(i d_1) + ... + exp(i d_n), where i denotes the imaginary<br /> unit and d_1,...,d_n the values of the torsion angle (in radians)<br /> in the n selected structures.<br /> <br /> Optionally, the &#039;&#039;integer&#039;&#039; angle index can be replaced by a string<br /> consisting of the angle name and the residue number, separated by a<br /> blank or a period, &#039;&#039;&#039;.&#039;&#039;&#039;.</div>
