- <ul>
- <li><em>label</em><br> Indicates that the feature

- </em></li>
-
- <li><em>score</em><br> Indicates that the feature
- score should be used to create a graduated colour for features of
- this type, in conjunction with mincolor, maxcolor.<br><em>This keyword was added in Jalview 2.11.
- It may be omitted (score is the default) if mincolor and maxcolor are specified.
- </em></li>
-
- <li><em>attribute|attName</em><br> Indicates that the value of feature
- attribute 'attName' should be used to create a colour for features of
- this type.
- <br>For example, <em>attribute|clinical_significance</em> to colour by clinical_significance.
- <br>To colour by range of a numeric attribute, include <em>mincolor</em> and <em>maxcolor</em>, or omit to colour by text (category).
- <br>(Note: the value of the attribute used for colouring will also be shown in the tooltip as you mouse over features.)
- <br>A sub-attribute should be written as, for example, CSQ:IMPACT.
- <br><em>This keyword was added in Jalview 2.11</em></li>
-
- <li><em>mincolor</em> and <em>maxcolor</em><br> Colour
- triplets specified as hexadecimal or comma separated values
- (may be left blank for a <em>label</em> style colourscheme,
- but remember to specify the remaining fields)</li>
-
- <li><em>absolute</em><br> An optional switch
- indicating that the <em>minvalue</em> and <em>maxvalue</em>
- parameters should be left as is, rather than rescaled
- according to the range of scores for this feature type.</li>
-
- <li><em>minvalue</em> and <em>maxvalue</em><br>
- Minimum and maximum values defining the range of scores for
- which the colour range will be defined over.<br>If minvalue is
- greater than maxvalue then the linear mapping will have
- negative gradient.</li>
-
- <li><em>novalue</em> <br>
- Specifies the colour to use if colouring by attribute, when the attribute is absent.
- Valid options are <em>novaluemin, novaluemax, novaluenone</em>, to use mincolor, maxcolor, or no colour.
- <br>If not specified this will default to novaluemin.</li>
-
- <li><em>thresholdtype</em><br> Either
- "none", "below", or "above". <em>below</em>
- and <em>above</em> require an additional <em>threshold
- value</em> which is used to control the display of features with
- a score either below or above the value.</li>
