Hi I fully appreciate the fact that the visualization module is still in development - although, I am looking very much forward to use it. In the meantime, is there a way to remove the link "view in GeneTrack" you get for all the BED files in your history? I am running changeset 3545 and I have the following lines commented in my 'universe_wsgi.ini' file: # Uncomment following line below to enable visualization module #enable_tracks = True # Comma separated list of UCSC / gbrowse browsers to use for viewing #ucsc_display_sites = main #gbrowse_display_sites = main # Define your GeneTrack servers in tool-data/shared/genetrack/genetrack_sites.txt #genetrack_display_sites = Nevertheless, I get a link like: http://galaxy-dev.fmi.ch/display_application/d12c5c8ceaef53e4/genetrack_inte rval/genetrack which (if clicked on) results in an Error with the following message: "Exception: A data display parameter is in the error state: genetrack_file" I am running another course next week promoting the use of our local galaxy server, and people will probably stumble across this broken link Thank you very much for your help Hans
