Hello Stewart, Many issues with Trackster are currently being addressed and a large set of changes is planned for release to Main early next year. Once published, more feedback about this newer tool would be great! For now, you are welcome to use the in-progress version of the changes that have been done already on the test server http://test.g2.bx.psu.edu/. This morning I am able to load the RefSeq track (complete) in BED format from UCSC there and view chr1 coverage. Please note that not all functionality is active and things can change unexpectedly on the test server! If you want to stay on Main or have specific visualization requirements, please use the links to GeneTrack, Ensembl, and [back to] UCSC. Thanks for your patience while we develop and deploy this new tool! Jen Galaxy team On 12/15/10 2:23 PM, Stewart Noyce wrote:

Attempted to demo trackster visualization on the main site (main.g2.bx.psu.edu) today.

- Logged in as required. - Used the _USCS Main_ table browser to download a coverage file in the bed format for hg18. - Viewed the first MB of four column data (chrom, chromStart, chromEnd, name), which clearly contains annotation data for 'chr1'. - Clicked on the _visualization in Trackster_ glyph. - Created a Human browser with a Dbkey of hg18. - Added the downloaded file as a track. - Selected chr1 and nothing shows up in the visualization screen. - Clicked through all magnification levels and moved left to right through the chromosome view.

Am I missing something, or is this a bug?

Stewart
