The bigBed format also offers a wide range of customization options for the display, from decorators to highlights. Additionally, it offers extensive filter controls, searching options, and mouseover configurations. Our trackDb documentation contains a full listing of settings available for the format.
Here is the bigBed configuration with some commonly used settings, including filtering and mouseover configuration.

You can use bigWig to tracks to display continuous annotations, such as RNA-seq expression, conservation scores, or other genome signal scores. You can build a bigWig using one of two plain-text formats: wiggle or bedGraph.

Next, we'll provide a basic overview of how to group your tracks using composite tracks and super tracks. This will allow you to pull similar data together under a single container.
Composite tracks can hold multiple tracks of the same type. For example, you use a composite to group together a set of RNA-seq experiments, including replicates.

Super tracks are a more general type of container. They can contain tracks of different types and even composites.
Configuring a basic super track is quite similar to composite tracks. There are two key components of a composite: (1) the line "superTrack on" in the parent track stanza, and (2) including "parent superTrackName" for each track that will be part of the super track.

If you plan to share your track hub more widely, you will want to create a description page for your tracks. A description page could contain a short description of what the data represents, how the data was generated, a link to the associated paper, or a contact email for questions regarding the data. Multiple tracks can use the same description page.
We provide an example description html that you can modify with
the details for your track. Once you've modified this example html for your
track, add an html to the corresponding track stanza:
