Genome and annotation tracks

Genome track

The genome track shows:

  • the current genomic axis

  • coordinate ticks

  • base letters when zoomed in enough

  • annotation features over the genome

At close zoom, individual bases can be drawn directly on the reference track.

Annotation track

The annotation track shows genome features in a dedicated lane above the genome track.

This is useful when you want a cleaner feature view without the genome-axis overlay.

Multi-exon features

For multi-exon genes:

  • the annotation track shows separate exon blocks connected across the intron

  • the genome track shows full-height exons with reduced-height introns between them

This makes exon structure visible at a glance.

Interaction

You can:

  • click features to select them

  • double-click features to activate them

  • double-click empty space to recenter the view

Selected features can be inspected in the right-hand panel.
