Re: [Gmod-ajax] Combining BigWig Tracks

[Colin <col...@gm...>]

I think this is sort of related to your last question (xref
https://sourceforge.net/p/gmod/mailman/message/37078566/)

I took a little shortcut and made an abbreviated config in that thread, but
if you add the storeClass to the track config, then the Combination track
recognizes it properly and should allow it


var storeName = JBrowse.addStoreConfig(null, {
  browser: JBrowse,
  type: "JBrowse/Store/SeqFeature/BigWig",
  baseUrl: ".",
  urlTemplate: "sample_data/raw/volvox/volvox_microarray.bw",
});
JBrowse.publish("/jbrowse/v1/v/tracks/replace", [
  { label: "My Track2", store: storeName, storeClass:
"JBrowse/Store/SeqFeature/BigWig" },
]);

Note that we don't use combination tracks often so there are probably some
weird corners there, but I am curious how your experience goes
