After uploading a custom track to the UCSC browser, you can update the track line: change the track's color, edit its name, etc.
track type=bedGraph name=sample_name desc=sample_description visibility=2 maxHeightPixels=50:30:11 color=50,50,180 alwaysZero=on
However, when I try to edit the description field (which then appears like a title above the track in the browser), it won't change from whatever it was when the custom track was uploaded.
I also tried removing the field completely but the description still doesn't change... Does anyone know how to go around this?
