23 <title>Alignment RNA Structure Consensus Annotation</title>
27 <strong>Alignment RNA Structure Consensus Annotation</strong>
30 <p>The RNA structure consensus displayed below the alignment gives
31 the percentage of valid base pairs per column for the first
32 secondary structure annotation shown on the annotation panel. These
33 values are shown as a histogram labeled "StrucConsensus",
34 where a symbol below each bar indicates whether the majority of base
37 <li>'(' - Watson-Crick (C:G, A:U/T)</li>
38 <li>'[' - Non-canonical (a.ka. wobble) (G:U/T)</li>
39 <li>'{' - Invalid (a.k.a. tertiary) (the rest)</li>
41 <p>Mousing over the column gives the fraction of pairs classified
42 as Watson-Crick, Canonical or Invalid.</p>
45 By default this calculation includes gaps in columns. You can choose
46 to ignore gaps in the calculation by right clicking on the label
47 "StrucConsensus" to the left of the structure consensus
50 <strong>RNA Structure logo</strong><br /> Right-clicking on the
51 label allows you to enable the structure logo. It is very similar to
52 a sequence logo but instead shows the distribution of base pairs.
53 There are two residues per column, the actual column and the
54 interacting base. The opening bracket is always the one on the left
55 side. <br> Like <a href="consensus.html#logo">sequence
56 logos</a>, the relative amount of a specific base pair can be
57 estimated by its size in the logo, and this can be made more obvious
58 by <em>normalising</em> the logo (enabled via the popup menu). When
59 the logo is displayed, the tool tip for a column gives the exact
60 percentages for all base pairs at that position.
