How to hide tracks that are the source for track collection?

[Aleksei Mironov]

Dear UCSC,

I am motivated by the track collection "GTEx RNA-Seq Coverage" provided for hg38.

I would like to build a similar collection with my bigwig files.

For now, I have a track hub with these bigwig files available in the following session:

https://genome-euro.ucsc.edu/s/magmir71/Test_session

Out of several bigwig files from the hub, I created a track collection named "Test_collection".

Now, I see the tracks twice: within the hub and within collection (see that attached figure).

Is there a way to have custom tracks in the collection such that they are only accessible within this collection, as in "GTEx RNA-Seq Coverage"?

Best,

Aleksei

Hello, Aleksei.

Thank you for your question about track hubs and track collections in the UCSC Genome Browser.

Track Collections purposefully duplicate the tracks. However, you can set the visibility to "hide" for the non-Collection version of the track. To do so, just right-click the track and select "hide" at the top of the right-click menu.

If you want more information about organizing tracks in a track hub hosted on your own server, you can see our documentation:

• trackDb docs for grouping tracks: https://genome.ucsc.edu/goldenPath/help/trackDb/trackDbHub.html#groupingTracks
• Quick-start guide for grouping tracks: https://genome.ucsc.edu/goldenPath/help/hubQuickStartGroups.html

I hope this is helpful. If you have any further questions, please reply to gen...@soe.ucsc.edu. All messages sent to that address are archived on a publicly-accessible Google Groups forum. If your question includes sensitive data, you may send it instead to genom...@soe.ucsc.edu.
