+<p><strong> RNA Helices Colouring </strong></p>
+<p>An RNA alignment loaded from a Stockholm file can be coloured
+ based on its helices. The helices are determined from the
+ secondary structure line in the Stockholm file (#GC SS_cons)
+ written in WUSS notation
+ that specifies base pairing. See <a href="http://en.wikipedia.org/wiki/Stockholm_format">
+ Wikipedia</a> or <a href="http://jalview-rnasupport.blogspot.com/2010/06/parsing-wuss-notation-of-rna-secondary.html">
+ Jalview RNA Support Blog</a> for more information about Stockholm files and WUSS notation.</p>
+Select "Colour" <strong>→</strong> "
+ By RNA Helices" to colour the alignment by RNA helices. <br>
+ <br>
+<p><em>Features</em></p>
+<ul>
+<li>Colours are generated randomly for the number of helices present.
+Reselect the "By RNA Helices" option to generate another set of random colors. </li>
+<li>Sequence logo is in <a href="purinepyrimidine.html">
+Purine/Pyrimidine colour scheme</a>. </li>
+<li>Line above the "Secondary Structure" line in annotation panel is WUSS notation present
+in the input file.</li>
