BigWig Data Fetcher for HiGlass

Quickly load data from a bigwig file in HiGlass.

Usage

The live scripts can be found at:

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

First, register the data fetcher:

import register from "higlass-register";
import { BigwigDataFetcher } from "higlass-bigwig-datafetcher";

register(
  { dataFetcher: BigwigDataFetcher, config: BigwigDataFetcher.config },
  { pluginType: "dataFetcher" }
);

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

[...
  {
    "type": "bar",
    "height": 80,
    "data": {
      "type": "bbi",
      "url": "https://aveit.s3.amazonaws.com/higlass/bigwig/example.chr1.10000-1160000.bw",
      "chromSizesUrl": "https://aveit.s3.amazonaws.com/higlass/data/sequence/hg38.chrom.sizes",
    },
    "options": {
      ...
    }
    
  }
]

Note that the chromSizesUrl option is required.
