&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;
Synopsis: idr(&amp;#039;&amp;#039;integer&amp;#039;&amp;#039;) = &amp;#039;&amp;#039;integer&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
This function returns the residue index of the dihedral angle with&lt;br /&gt;
the given dihedral angle index.&lt;br /&gt;
&lt;br /&gt;
The residues are indexed from 1 to nr according to the sequence&lt;br /&gt;
declared in the sequence file. The (external) residue number that&lt;br /&gt;
is used to identify a residue in the input files can be different&lt;br /&gt;
from the (internal) residue index. The function &amp;#039;&amp;#039;&amp;#039;rnum&amp;#039;&amp;#039;&amp;#039; can be used&lt;br /&gt;
to obtain the external residue number of from the residue index.&lt;br /&gt;
&lt;br /&gt;
Optionally, the &amp;#039;&amp;#039;integer&amp;#039;&amp;#039; dihedral angle index can be replaced by a&lt;br /&gt;
string consisting of the dihedral angle name and the residue number,&lt;br /&gt;
separated by a blank or a period, &amp;#039;&amp;#039;&amp;#039;.&amp;#039;&amp;#039;&amp;#039;.&lt;/div&gt;</summary>
