See what gbatlas can do
gbatlas is a browser-based viewer for GenBank and GenPept records.
The screenshots below show the main things it does:
- Read a GenBank record as a feature map
- View a circular molecule as a ring
- Filter the map by feature type
- Translate a CDS with the record’s genetic code
- Find open reading frames
- Map restriction sites
- Read the annotated source text
- Open a multi-record file
Files are processed in the browser, on your own machine — nothing is sent over the network.
Read a GenBank recordThe core view: annotated features laid out along the molecule, with the record summary above and the sequence below.
View a circular molecule as a ringA circular record also gets a ring view beside the linear map.
Dragging the ring rotates the shared viewport, and the linear map follows.
Filter the map by feature typeFeature types are listed with their counts; switching one off removes it from both the map and the source panel, so a crowded record can be read one layer at a time.
Translate a CDS the way the record saysA CDS is translated with the record’s own genetic code and its /codon_start, not a hardcoded standard table.
Where the stored /translation disagrees with a plain translation, gbatlas says so instead of hiding it.
Find open reading framesAn optional computed layer draws ORFs alongside the annotated features — useful on a record whose annotation is thin or absent.
Computed marks are kept visually distinct from what the file declares.
Map restriction sitesA second computed layer maps restriction sites onto the molecule, with the site count and a cutter filter.
On a circular record the ticks appear on the ring as well.
Read the annotated source textThe original GenBank text stays available beside the map, with each feature block addressable — selecting a feature in one pane highlights it in the other.
Open a multi-record fileA file holding several records opens as one document with a record picker; switching records swaps the whole view — map, source and sequence.
