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](https://www.python.org/downloads/) if needed.

### Install with pip (recommended)

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

```bash
pip install BiNgoViewer
bingo
```

Options:

```bash
bingo                    # launch on default port 8000
bingo --port 9000        # use a custom port
bingo --no-browser       # start without opening the browser
bingo --install          # create a desktop shortcut
bingo --update           # check for updates
bingo --version          # show installed version
bingo --no-update        # skip automatic update check
```

### 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:
> ```bash
> chmod +x Install_macOS.command
> ```

### Docker

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

```bash
cd app
docker compose up --build
```

Then open [http://localhost:8000](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, drag and drop, or paste a local file path (recommended for large BAM files).
2. **Navigate** — Left-click drag to pan, scroll to zoom, use the chromosome scrubber to jump across the genome.
3. **Select regions** — Right-click drag to select a region; hover for stats (coverage, variants, reads).
4. **Zoom to gene** — Double-click a gene annotation to zoom in with context.
5. **Track settings** — Adjust height, color, scale, bar width, peak outline trace, and nucleotide display.
6. **Reorder tracks** — Drag the grip handle on any track label.
7. **Export** — Save the current view as SVG or PNG with layered groups.
8. **Save session** — Export/restore your entire workspace including zoom, colors, and settings.
6. **Save session** — Store your workspace and restore it later.

## API Documentation

When the server is running, interactive API documentation is available at:
- **Swagger UI**: [http://localhost:8000/docs](http://localhost:8000/docs)
- **ReDoc**: [http://localhost:8000/redoc](http://localhost:8000/redoc)
