Update: Please try using IGV or UCSC instead. Mark Trackster as deprecated in the UI · Issue #658 · galaxyproject/usegalaxy-tools · GitHub
Ah… I remember!! The buttons do not stay active when hovering over them. Forgot.
This will not be fixed. Try using IGV instead. Trackster is legacy – we keep it around because we try not to remove anything, but it should probably be at least marked as deprecated.
We don’t post movies here … but the buttons flicker between these two states, when the cursor moves over the buttons they flicker away.
I think this was only for some datatypes, not all, but cannot remember which. Definitely a problem for BAMs, as in the example above.
Sorry for the confusion and hope that helps!
I decided to make a ticket for the problem, please see if interested → Mark Trackster as deprecated in the UI · Issue #658 · galaxyproject/usegalaxy-tools · GitHub
