Use this component to paint a track that uses the sequence to paint a color depending on each residue.
Useful to display hydrophobicity, isoelectric points, or any feature were a color can represent a residue.
<protvista-coloured-sequence length="770" scale="hydrophobicity-scale" />
The sequence to use for the track.
The scale attribute is the mapping between a residue and a numeric value.
The value of this parameter could be either one of the predifined scales, or a custom scale indicating the values.
The list of predefined scales:
The format for the custom scale is a comma separated list of pairs. Where each pair is a [KEY]:[VALUE]. For example:
If a residue in the sequence is not defined in the used scale, the value used will be 0.
The color range attribute allow to define the colors to use when painting the values.
The component will use this range to create a scale that can be interpolated.
The default color_range is
#ffdd00:-2,#0000FF:2 indicating that a value of
-2 should be painted Yellow (
a value of
2 should be blue (
#0000FF). And values in between will be interpolated.
The format requires at least 2 points, and if more than 2 are given, the interpolation would be calculated in between segments.
white is now representing the value
Notice that HTML color names are also supported, as in the example above.
start: number (optional)
The start position of the selected region.
end: number (optional)
The end position of the selected region.
highlight: string (optional)
A comma separated list of regions to highlight.
Each region follows the format:
[start]:[end], where both
[end] are optional numbers.
