# GFF Data Fetcher for HiGlass

Quickly load data from a GFF file to create a gene annotations track in HiGlass.

[![HiGlass](https://img.shields.io/badge/higlass-🌸-brightgreen.svg)](http://higlass.io)

This is the source code for multivec tracks in HiGlass only; for the rest of HiGlass,
see these repositories:

- HiGlass viewer: https://github.com/hms-dbmi/higlass
- HiGlass server: https://github.com/hms-dbmi/higlass-server
- HiGlass docker: https://github.com/hms-dbmi/higlass-docker

## Usage

The live scripts can be found at:

- https://unpkg.com/higlass-gff-datafetcher/dist/higlass-gff-datafetcher.min.js

Configure the track in your view config; you should be all set from here!

```
[...
{
"type": "horizontal-gene-annotations",
"height": 80,
"data": {
"type": "gff",
"url": "https://pkerp.s3.amazonaws.com/public/GCF_001461035.1_ASM146103v1_genomic.gff.gz",
"chromSizesUrl": "https://domain.com/my.chrom.sizes",
"options": {
"namePaths": [
"gene",
"annotationName"
]
}
}
}
]
```

Note that the `chromSizesUrl` option is optional and only needs to be provided if the gff file lacks the `region` entries listing the chromosomes in the assembly.

For an example, see [`src/index.html`](src/index.html).

### Options

**namePaths** - A list (e.g. `['gene', 'annotationName']`) of attributes to look in when choosing the name of the region to display. The fetcher will go through the items in this option and use the first one that is present in the attributes.
**excludeTypes** - A list of types to exclude from the display.

## Development

### Testing

To run the test suite:

```
npm run test-watch
```

```bash
npm link higlass
```
