Gff3Adapter
Auto-generated config schema for the current JBrowse release — see the config guide for concepts. Provided by the gff3 plugin. View source.
Example usage
{
type: 'FeatureTrack',
trackId: 'my_track',
name: 'My track',
assemblyNames: ['hg38'],
adapter: {
type: 'Gff3Adapter',
uri: 'https://example.com/genes.gff3',
},
}
genes.gff3 infers Gff3Adapter and FeatureTrack on its own, and name defaults to the file name. In a config declaring one assembly, assemblyNames comes from there too — see the shortest track.
{
trackId: 'my_track',
uri: 'https://example.com/genes.gff3',
assemblyNames: ['hg38'],
}
See the Config slots section below for all available configuration fields.
used to load plain-text GFF3 files. Loads the whole file into memory, so prefer the Gff3TabixAdapter for large files.

Config slots
These slots go inside the track's adapter: "adapter": { "type": "Gff3Adapter", ... }. It also accepts the shorthand keys uri, baseUri in place of writing a location slot out. Slot types (fileLocation, frozen, ...) are explained in the config slot types reference. Slots a base configuration contributes are listed here too, so this table is the whole surface.
| Slot | Description |
|---|---|
gffLocationfileLocation = { uri: '/path/to/my.gff', locationType: 'UriLocation' } | location of the GFF3 file. May be gzipped; it is decompressed and parsed in full on first use, so the file has to fit in memory. |
