+<body><p><strong>Alignment RNA Structure Consensus Annotation</strong></p>
+
+<p>The RNA structure consensus displayed below the alignment is the
+percentage of valid base pairs per column. It is calculated in
+relation to a secondary structure and just paired columns are
+calculated. The canonical Watson-Crick base pairings (A-T/U, G-C) and
+the wobble base pair (G-T/U) are regarded as valid pairings.<br>
+The amount of valid base pairs is indicated by the profile in the
+Alignment Annotation row.<br>
+By default this calculation includes gaps in columns. You can choose
+to ignore gaps in the calculation by right clicking on the label
+"StrConsensus" to the left of the structure consensus bar
+chart.<br>
+
+<p><strong>Structure logo</strong></p>
+By clicking on the label you can also activate the structure logo. It is very
+similar to a sequence logo but counts the numbers of base pairs. There
+are two residues per column, the actual column and the interacting
+base. The opening bracket is always the one on the left side.<br>
+Like sequence logos the relative amount of a specific base pair can be
+estimated by it's size in the logo. The tooltip of a column gives the
+exact numbers for all occuring valid base pairs.
