v3.5.1 Release

· 4 min read

Hi all, This has a number of small bugfixes and features. Here are a couple highlights

Better dropdown menus​

In previous releases, the dropdown submenus would close the instant your mouse left their boundaries, but now, they stay open until you select a menu item or click away. This can be very useful when accessing nested submenus

Ability to customize root configuration​

We added the ability for plugins to add new entries to the root configuration. This now makes it possible to add easy-to-access configuration for your plugin. Example:

export default class MsaViewPlugin extends Plugin {
  name = 'MyPlugin'

  install(pluginManager: PluginManager) {}

  configure(pluginManager: PluginManager) {}

  rootConfigurationSchema(pluginManager: PluginManager) {
    return {
      mything: ConfigurationSchema('MyConfig', {
        greetings: {
          type: 'string',
          defaultValue: 'hello world',
        },
      }),
    }
  }
}

A user could then customize their greeting in a new way like

{
  "assemblies": [...],
  "tracks": [...],
  "plugins": [...],
  "mything": {
    "greetings": "hello jbrowsers"
  }
}

This can then be used in your code by readConfObject(session.jbrowse, ['mything','greetings'])

Here is an example used by the MSA view plugin https://github.com/GMOD/jbrowse-plugin-msaview/blob/7027f01abe2b4253fd2a250021d2b13a1b4f2fce/src/index.ts#L37-L59

We anticipate that this will enable new and easier plugin customizations

Allow user to draw only matches in synteny view​

The synteny view can display long alignments, including insertions and deletions. However, particularly in chain files, the specific "insertion/deletion" markers are less meaningful as a large insertion+deletion pair is often used to connect more high-scoring alignments across large distances

Removal of the "Start screen" from jbrowse-web​

This release removes the "start screen" from jbrowse-web. Instead of showing the start screen, users are just dropped straight into the main jbrowse 2 interface. This will hopefully "drop users into the action" faster.

Bug fixes​

Some notable bug fixes include

  • Fix for loading bigwig files created by bigtools (a newer Rust-based bigwig toolkit)
  • Fix for certain breakpoint split view workflows fetching too much data and freezing

v3.4.0 Release

· 4 min read

Hello all, this release adds a small set of features and bugfixes

Improved gene name searching​

We added a fuzzy finder library (uFuzzy) that helps prioritize the results returned by our text search (e.g. trix), so gene name searching should provide much more relevant results

Updated documentation with new screenshots​

We updated gallery (https://jbrowse.org/jb2/gallery/) with new screenshots and live links, and are rolling out updated screenshots throughout the docs pages to be more up to date and high quality

Misc​

We also fixed a bug in methylation/modifications rendering that caused crashes in v3.2.0-v3.3.0 and updated Electron to v36 (which now uses GTK4 on linux)

v3.3.0 Release

· 4 min read

Hello all,

This release adds a significant update to the multi-variant renderer that allows it to be used for visualizing structural variants Previously, all variants >10bp were filtered out, with the idea that overlapping variants are too difficult to interpret

This PR now allows drawing large structural variants in the multi-sample variant display type. It will actually draw long, even overlapping, structural variants!

image

Figure: Screenshot showing many SV calls over a 5Mbp+ region from the 3,202 human samples from the 1000 genomes project, with a large "inversion" variant showing the shaded triangles. The right side panel shows the feature details for this inversion variant showing the new genotype frequency panel, indicating about 47% of samples have a 'heterozygous' inversion call here

image

Loading a random track, and turning on the arc display, there are indications of a large variant for a random sample here (green and navy arcs indicate discordant read pairing associated with inversion)

We hope that you enjoy these new features! The visualizations may be visually complex but we hope it can be a magnifying glass to reveal important patterns of your datasets! Feel free to let us know if you have any feedback

v3.2.0 Release

· 3 min read

Hello all,

This release includes a new ability to provide simplified snapshots to the linear genome view, a new built-in clustering method for genotypes, and more

In-app clustering​

In recent versions, we provided the ability to cluster genotype and multi-wiggle tracks, however we provided an R script for users to perform clustering externally and import the results

With this release, we have added a basic in-app clustering workflow, greatly improving the ease-of-use of this feature

image

Screenshot of the in-app clustering user interface

Renamed embedded packages and restored vanillajs builds​

We have renamed our embedded packages

  • Renamed @jbrowse/react-linear-genome-view -> @jbrowse/react-linear-genome-view2
  • Renamed @jbrowse/react-circular-genome-view -> @jbrowse/react-circular-genome-view2
  • Renamed @jbrowse/react-app -> @jbrowse/react-app2

Motivation: our vanillajs builds, which people often pointed to the "latest" release on from CDN networks, were no longer able to be updated in a backwards compatible way.

Therefore, we have renamed the packages, and updated tutorials.

This allows us to continue updating the package without any breakage for existing users. Please let us know if you run into any issues!

v3.1.0 Release

· 3 min read

This release adds several interesting features including

Sticky view headers and pinned tracks​

We created a new UI where the "view header" stays visible even when scrolling the page.

We also added the ability to "pin" tracks in the linear genome view, which also stay visible when scrolling the page.

Cluster multi-quantitative tracks​

Motivated by the clustering workflow in the Multi-variant viewer, a similar feature was added to the multi-quantitative track

To do this, we sample the data according to the current zoom level (otherwise, it would create very large matrices at per-base resolution) and then provide an R script the user can run to cluster the data

Simplify some adapter configuration​

The configuration system has a lot of complex substructure, but in this release we created the ability to supply a simplified config, and the results will be auto-determined

For example

{
  "type": "AlignmentsTrack",
  "trackId": "volvox_alignments",
  "name": "volvox-sorted.bam",
  "assemblyNames": ["volvox"],
  "adapter": {
    "type": "BedGraphTabixAdapter",
    "bedGraphGzLocation": {
      "uri": "file.bed.gz"
    },
    "index": {
      "location": {
        "uri": "file.bed.gz.tbi"
      }
    }
  }
}

after

{
  "type": "AlignmentsTrack",
  "trackId": "volvox_alignments",
  "name": "volvox-sorted.bam",
  "assemblyNames": ["volvox"],
  "adapter": {
    "type": "BedGraphTabixAdapter",
    "uri": "file.bed.gz"
  }
}

The CLI tools and other systems will continue to output the verbose version for the time being, but this simplified system will be handy to anyone who does hand-coding of the configuration
