Re: [Gmod-ajax] How to add more fields to faceted selector

[Vaneet L. <van...@uc...>]

Hey Colin,

Thank you so much for fixing that!  Sorry I meant to get back to you sooner about this, but I did notice one further issue with the faceted track selector.  Now when you open the faceted track selector it does in fact escape the HTML so that you see actual links and don’t see the hidden HTML tags which is good.  However, as soon as you start typing search terms and it reveals which items are matching your search query on the fly, all the results below that match with their unescaped HTML tags.  Is that something that can be fixed or it has to be this way for the faceted selector to work with escaped HTML?

Thanks,

Vaneet

It is now fixed on the main branch (jbrowse create --nightly) if you want to try it

Fix here https://github.com/GMOD/jbrowse-components/pull/5492

Hey Colin,

Thank so much for adding that update so quickly into a new release.  The searching of additional metadata fields does work very well but there’s a new issue I noticed.  It appears now that if I have any HTML in those metadata fields which for my purposes was used for sorting as well as adding links to the ‘About this track’ window, the HTML is not escaped now in the faceted track selector window and just shows as the raw HTML with all the opening and ending tags.

I can’t quite remember now but I’m pretty sure this wasn’t happening before in a previous release.  I remember looking at the metadata in the faceted track selector in previous releases and it was escaped so that the text appeared as a link when I had put in the necessary HTML to do that.  The about this track window still appears correctly as before with escaping the necessary HTML so it’s not seen.

Is this something you can fix?

Thanks,

Vaneet

Searching metadata in the faceted selector was fixed and released in v4.1.13. Let me know if you run into any other issues

I don't think so. I'll made a tracking issue for this here https://github.com/GMOD/jbrowse-components/issues/5472

Hey Colin,

Just a follow up to this old topic…thank you for the info by the way!  Is there any way to search other fields in the faceted track selector besides the track name?

I realize that when there are metadata attributes that are shared across more then 5 tracks those attributes do appear as facets and you can click on the facet filters to filter out the results by their values.  However, what I’m wondering is there any way to search those additional facets on their values from the main search bar of the faceted track selector, or does it only simply search the tracknames?

Thanks,

Vaneet

The basic idea for the faceted track selector is that any "top level" entry in the track metadata becomes searchable in the track metadata.  Example

{
      "type": "VariantTrack",
      "trackId": "volvox_test_vcf",
      "metadata": {
        "thing here": "hello"
      },
      "name": "volvox 1000genomes vcf",
      "assemblyNames": ["volvox"],
      "category": ["Variants"],
      "adapter": {
        "type": "VcfTabixAdapter",
        "uri": "volvox.test.vcf.gz"
      }
    },

That will make "thing here" a column and a facet filter, but also note that it filters out "sparse" metadata columns by default, so it only shows metadata that is shared across >5 tracks as a facet (arbitrary threshold)

You can toggle "Show sparse metadata columns" to show facets for even metadata not shared by 5 tracks



There is no notion of only a subset of tracks appearing in the faceted selector currently

Hi,

There is documentation for adding the field ‘category’ as an active field to the faceted track selector.  How do you add more fields to that so they can be used to filter tracks for in that pop up window?  I tried added some random fields under the ‘metadata{}’ name in the config.json file.  While they appear in the ‘About this track’ dialog they don’t appear in the faceted track selector.

Also, is there a way I can limit which tracks I want to appear in the faceted track selector?  I want a subset of tracks that can appear in their own faceted track selector with many metadata fields to filter upon similar to the original JBrowse.  How do I do this in JBrowse 2?

Thanks,

Vaneet
