Here are the steps to create this visualization; this is relatively new 
functionality, and you'll want to use our test server ( ) for now.

(1) Create a new visualization from the main menu: Visualization --> New Track 
Browser and choose your genome build.
(2) Add your Cufflinks GTF files to the visualization using the 'Add Tracks' 
button in the upper right of the visualization. (Adding the Tophat reads and/or 
annotation tracks might prove useful as well.)
(3) Zoom in (use the button at the top, double click on a point, or drag to 
select an area on the genome coordinates at the top) until the track's menu has 
the option 'Show filters' and choose this option to show filters.
(4) Once filters are visible, you should be able to drag the slider to 
dynamically filter transcripts.

Here's an example visualization of some mapped Tophat reads and Cufflinks 
transcripts that you can try out:

We're continuing to refine and extend this functionality and the Galaxy Track 
Browser in general; questions/comments/suggestions are most welcome.
