color scheme for mapping quality

[yeeus]

Hello, I'm using jBrowse2 to visualize my alignment track. It's useful for me to show the mapping quality by the seting "color scheme". However, I want to know the mapping quality score range each color representing. How can I get this information?
Best wishes!

hi there, it is a bit tricky because we don't properly have legends on our tracks. essentially the color is a HSL map

the function that does it is

export function colorByMappingQuality(feature: Feature) {
  return `hsl(${feature.get('score')},50%,50%)`
}

where score is the "MAPQ" value, and the value in practice ranges from about 0-100 (high quality illumina reads that i see have mapq of about 70)

so an example legend showing 0-100 mapq is here

hope that helps, we will keep the concept of adding legends on the radar so that it is not so unclear

note that the per-base quality color scale is a little different, but the above one is the MAPQ
