CoverageBand

Auto-generated from the config schema in the source — see the config guide for concepts. Built into JBrowse core. View source.

The coverage histogram band of the alignments and MAF displays, their coverage setting: whether it draws, its height, the insertion and clip marks drawn in it, and which allele segments it colors. Its value axis is the display's scales.

Example usage

{ type: 'LinearAlignmentsDisplay', coverage: { height: 80 } }
{ type: 'LinearAlignmentsDisplay', coverage: { show: false } }

Config slots

A setting written to it names members one by one: a member left out stays as it is, and null resets one. Slot types (fileLocation, frozen, ...) are explained in the config slot types reference. Slots a base configuration contributes are listed here too, so this table is the whole surface.

SlotDescription
show
boolean = true		draw the coverage band
height
number = 45		height of the coverage band in pixels
showInterbaseIndicators
boolean = true		draw the insertion and clip count bars and their indicator triangles
minAlleleFraction
number = 0		A color rule, beside the pileup's fadeLowFrequency, which fades its marks by the same per-base share through a depth-dependent threshold. The band's grey depth bar shows through where a segment is not colored.
