Hello UCSC Genome Browser team,

I have a track hub here that I am using in this public session that I have built referring to this documentation.

From the debugging that I have been able to complete from my side, it appears that the comma-separated definitions for the detailsDynamicTable stanza line are being ignored and will only show the first provided table.

For example, if my trackDb.txt file contains this line:
detailsDynamicTable jsonMolecular|Molecular Features,jsonClinical|Clinical Features,jsonPublication|Publication

Then I only get the Molecular Features table shown.

If I remove the Molecular Features table:
detailsDynamicTable jsonClinical|Clinical Features,jsonPublication|Publication

Then I get the Molecular Table field as a normal extension field with the json string as the value and only the Clinical Features table shown.

NOTE: in all three cases, the data are successfully shown when I navigate to the "Data schema/format description and download" page.

Is there something incorrect on my end from interpreting the documentation or is this a bug?

Best,
Shane Buckley

Hi Shane,

I'm taking a look now, from a first glance it looks like everything is right on your end though.

Hi Shane,

This was indeed a bug on our end, we have fixed it on our test server. I made a session on our test server with your test hub attached:

So you can verify everything is hunky dory. This change will be reviewed by our QA team and released to the public site some time around April 28. 

Thanks!

Thanks! 

One small issue I still see is that the tables appear in reverse order. From what I provided, I would expect it to be Molecular, Clinical, then Publication.

Best,
Shane

Hello, Shane.

Thank you for letting us know. However, changing something like this is low on our priorities and unlikely to be fixed anytime soon. I would recommend just changing the order of the tables in your file so that they come out in the desired order.

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.
