20 <title>Sequence feature colour schemes</title>
24 <p><strong>Sequence feature colour schemes</strong></p>
25 <p>Jalview can visualize annotation present on parts of a sequence by
26 overlaying colours according to the annotation present at each position.
27 It allows features to be colored either according to type, or for a
28 particular type, according to an individual feature's associated label
29 or score. The <a href="featuresettings.html">Feature Settings dialog
30 box</a> controls the order and display of each sequence annotation type, and
31 also allows the colour scheme used for the the feature to be changed <em>via</em>
32 the 'Graduated Colour' option in the sequence feature pop-up menu
33 (obtained by right-clicking on a sequence feature).</p>

36 feature colour scheme settings dialog box</img></center>
37 <p>The Graduated Feature Colour dialog box has the following
40 <li><em>Colour by Label</em> - when checked this derives a colour
41 for each feature based on the label text.</li>
42 <li><em>Min and Max Color boxes</em> - Click on these boxes to set
43 the minimum and maximum colours used to shade features by their
44 associated score.</li>
45 <li><em>Threshold type combo box</em> - Allows features to be
46 hidden features if their score is below or above a given threshold.<br />
47 <em>Set the threshold using the slider or type it in to the text
48 box. The threshold cannot be set outside the available range of feature
51 <li><em>Threshold is Min/Max</em> - When checked, the threshold
52 will be used as the upper or lower limit when shading the features
53 according to their score using the Min and Max colour.</li>
56 <p><strong>Icon styles for graduated feature styles</strong><br/>
57 <p>When a graduated colourscheme is applied to a feature, it is indicated in the feature settings or amend feature dialog box by the following types of icon:<br/>
58 <center><table width="50%" border="1">
59 <tr><td><strong>Type of Colouring</strong></td><td><strong>Icon</strong></td></tr>
60 <tr><td><em>Graduated colour by Feature Score</em></td><td><img src="fcsminmax.gif"/></td></tr>
61 <tr><td><em>Graduated colour thresholded (less than) by feature Score</em></td><td><img src="fcsltthan.gif"/></td></tr>
62 <tr><td><em>Graduated colour thresholded (greater than) by feature Score</em></td><td><img src="fcsgtthan.gif"/></td></tr>
63 <tr><td><em>Colour by Feature Label (may also be thresholded)</em></td><td><img src="fcsntlabel.gif"/></td></tr>
65 <td align="center" colspan="2">
67 <strong>The current threshold is given in the
68 icon's tooltip.</strong>
