Upload up to 30 mitochondrial genomes in GenBank format (.gb/.gbk/.gbff)
and generate the linearized genome map, the CDS/rRNA presence heatmap, and the
normalized-position distance heatmap. Downloads in PNG, SVG, and CSV (plus a ZIP with everything).
Tip: use the built-in self-tests below to validate parsing in your browser before uploading large files.
