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.
When you are zoomed out beyond nucleotide level, the AA / Annotation track can also
show six-frame stop-codon overview markers. These appear as theme-coloured vertical
markers under the annotation rectangles, similar to the overview in Artemis. Stop-free
stretches are left clear, so likely ORFs stand out by eye.
You can turn this on in the AA / Annotation track settings with Show stop codons.
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.
