Heat maps are used for data types which associate a value with a genomic position, Or region. As such, this track uses the same data format As histograms.
The track linearly maps a range Of values [min,max] onto a list Of colors c[n], i=0..N.
f = (value - min) / ( max - min ) n = N * f

Colors are defined by a combination of lists or CSV. Color lists exist For all Brewer palletes (see etc/colors.brewer.lists.conf) As well As For N-Step hue (hue-sN, e.g. hue-s5 = hue000,hue005,hue010,...) And N-color hue (hue-sN, e.g. hue-3 = hue000,hue120,hue140).
Which value To use for the color assignment:
0(默认值): the absolute value given in the data file1: the value as a fraction Of the plot min/max2: the value as a fraction Of the track min/max(see etc/tracks/heatmap.conf in the circos distribution)
If scale_log_base is used, the mapping is not linear, but a power law
n = N f*(1/scale_log_base)
When scale_log_base > 1 the dynamic range For values close To min Is expanded. When scale_log_base < 1 the dynamic range For values close To max Is expanded.
