23 <title>Annotation Colouring</title>
28 <strong> Annotation Colouring </strong>
30 <p>Jalview allows the columns of an alignment to be coloured using
31 any numerical annotation rows added to that alignment.</p>
32 Select "Colour"
33 <strong>→</strong> ".. by Annotation" to bring up the
34 Colour by Annotation settings window.
38 <img src="annotationColourSetting.gif" width="471" height="256">
41 <li>Select which annotation to base the colouring scheme on
42 using the top left selection box.<br />If the <strong>Per-sequence
43 only</strong> tick box is not greyed out, then ticking it will limit the
44 available annotation rows to just those that are sequence
45 associated (e.g. T-COFFEE scores and <a
46 href="../webServices/proteinDisorder.html"
47 >protein disorder predictions</a>), which will colour each sequence
48 according to its own per-residue scores.<br /> <em>Per-sequence
49 associated annotation colouring was introduced in Jalview 2.8</em>
51 <li>If the "Use Original Colours" box is selected,
52 the colouring scheme will use the colouring scheme present on the
53 alignment before the Annotation Colour Settings window was
54 displayed. <br /> <em><strong>Please Note:</strong> If no
55 colour scheme was applied previously, then the colours for lines
56 and labels at each position in the annotation row will be used,
57 for secondary structure symbols and graphs, this may be black by
58 default, so your alignment will be coloured black.</em>
60 <li><em>Secondary structure annotation colouring</em><br />By
61 default, Jalview will employ the helix or sheet colours to shade
62 sequences and columns by available secondary structure annotation
63 tracks. In the case of RNA, each structure is processed to
64 identify distinct RNA helices and rendered in the same way as the
65 <a href="rnahelicesColouring.html">RNA Helices shading scheme</a>.
66 <em>Structure based sequence shading was added in Jalview
68 <li>The colour scheme can display a colour gradient from a
69 colour representing the minimum value in the selected annotation
70 to a colour representing the maximum value in the selected
71 annotation. Use the "Min Colour" and "Max
72 Colour" to set the colour gradient range.
74 <li>Press the "Defaults" button to reset the
75 minimum and maximum colours to their default settings (these
76 are configured in the applet's parameters or the <a
77 href="../features/preferences.html"
78 >application's user preferences</a>.).<br /> <em>Default min
79 and max colours were introduced in Jalview 2.7</em>
83 <li>Select whether to colour the alignment above or below an
84 adjustable threshold with the selection box center left of the
86 <li>Change the threshold value with the slider, or enter the
87 exact value in the text box.</li>
88 <li>Select the "Threshold is Min/Max" checkbox to
89 assign colours using the thresholded range's minimum and maximum
90 values, otherwise the scale will be defined by the range of values
91 in the annotation row.</li>
