Works by accessing data from an Apollo server.

E.g., http://someserver.org/apollo/track/Honeybee/Official%20Gene%20Set%20v3.2/Group1.1/GB42168-RA.json

Deploy

1. Bump package number.
2. npm run-script pack
3. npm login # if not already
4. npm publish # if not already

Example Usage

From an example ReactJS environment (also working in VueJS and demo is in VanillaJS). Height is calculated on the fly for 'global' isoform tracks.

    let transcriptTypes = getTranscriptTypes();
    const configGlobal = {
      'locale': 'global',
      'chromosome': chromosome,
      'start': fmin,
      'end': fmax,
      'transcriptTypes':transcriptTypes,
      'tracks': [
        {
          'id': 1,
          'genome': this.props.species,
          'type': 'ISOFORM',
          'url': [
            this.trackDataUrl,
            '/All%20Genes/',
            `.json${nameSuffixString}`
          ]
        },
      ]
    };
    new GenomeFeatureViewer(configGlobal, 'genome-feature', 900, undefined);

Long Term Goal

The idea is that we can have multiple interactive tracks.

This is an example of how they might be used. The controls / filters can be used to interact and the details section could be part of that interaction.

The top genomic view is the "overview", consisting of a (very sad) variant track and an isoform track, though it could be any number. The red arrow at top indicates a selected region that is linked to the scrollable track at the bottom through a separate eventing model.
