enabling the default track visibility show option on a mirror

[kevin o riordan]

Hi 

I was wondering about changing the default on the sql trackDb for a super-track from hide to show. 

Now I know that the visibility setting to "full"/"2" for normal tracks but the show option does not appear to be documented.

I was wondering about where to set it.

Kind Regards

Hi Kevin,

Thank you for your question about superTrack visibility settings. Please note the information on the trackDb definitions page, under the "Supertrack settings" section, http://genome.ucsc.edu/goldenPath/help/trackDb/trackDbHub.html#superTrack:

To set a supertrack to display as default add the word show, superTrack on show, to the end of the statement.

For example, you would structure your trackDb statements like so:

track mySuperTrack
...
superTrack on show

    track mySubtrackA
    ...
    superTrack mySuperTrack full

These settings will make it so that a supertrack "mySuperTrack" and it's one subtrack "mySubtrackA" are both displayed by default.

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.
