BiNgoViewer 1.4.2

BiNgo Genome Viewer — a lightweight browser-based genomics viewer

BiNgo Genome Viewer

A lightweight, browser-based genomics viewer for visualizing genomes, coverage tracks, read alignments, variants, and annotations. Built as a modern alternative to IGV.

Supported File Formats

Type	Formats
Genome	GenBank (.gb, .gbk), FASTA (.fasta, .fa)
Coverage	BigWig (.bw), WIG (.wig), BedGraph (.bedgraph, .bdg)
Reads	BAM (.bam + .bai index)
Variants	VCF (.vcf, .vcf.gz)
Annotations	BED (.bed), GFF (.gff, .gff3), GTF (.gtf), GenBank (.gb)

Quick Start

Requires Python 3.10 or newer. Download from python.org if needed.

Install with pip (recommended)

No Node.js required — the frontend is pre-built and bundled.

pip install BiNgoViewer
bingo

Options:

bingo --port 9000        # use a custom port
bingo --no-browser       # start without opening the browser
bingo --install          # create a desktop shortcut

Windows (one-click)

Double-click Install_Windows.bat. It will install Python dependencies into a local environment and launch the viewer. No command line needed.

macOS / Linux (one-click)

Double-click Install_macOS.command (or run it from a terminal). It will create a virtual environment, install dependencies, and launch the viewer.

Permission denied? Run once in Terminal:

chmod +x Install_macOS.command

Docker

No Python or Node.js required — everything runs inside the container.

cd app
docker compose up --build

Then open http://localhost:8000.

Troubleshooting

Problem	Solution
python not found	Install Python 3.10+ and check Add to PATH during setup
pip install fails	Try pip install --user BiNgoViewer or use a virtual environment
Port 8000 in use	Run bingo --port 9000 (or any free port)
Browser doesn't open	Visit http://localhost:8000 manually
Server won't stop	The server auto-exits when you close all browser tabs; or press Ctrl+C

Usage

1. Load files — Use the file picker or drag and drop. Genome and track files are auto-classified by extension.
2. Navigate — Click and drag on tracks to pan; scroll wheel to zoom; use the coordinate bar to jump to a region.
3. Track settings — Click the gear icon to adjust height, color, scale, and bar width.
4. Reorder tracks — Drag the grip handle on any track label.
5. Export — Save the current view as SVG or PNG.
6. Save session — Store your workspace and restore it later.
