First of all, best wishes! I was/am trying to visualize a GTF file in galaxy on a local 64 bit ubuntu system. However I stumbled upon an issue were it remained grey. When I did an automaic visualization I saw a line that went up and down over the chromosome. When I switched to pack I got a grey / / / line slashed output. I contacted dannon and ceberhard on IRC and they told me to add a print statement on line 200 for the tracker. This visualized the following error: {'kind': 'error', 'message': '/bin/sh: 1: faToTwoBit: not found\n'} So I downloaded and placed the faToTwoBit file in /usr/bin I even chmodded it to 777 but the error remained. I also started digging into the code on where it calls the application and added /usr/bin/ in front of it but no luck so far. Anyone has a clue on what is happening? It almost must be an ubuntu related issue as I dont see how galaxy cannot find the path. $PATH is still properly set when running galaxy as I added echo $path it to a tool and it returned /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/bin The IRC chat can be seen here: http://pastebin.com/9fZrkRDn Thanks a lot, /home/galaxy/HB27.2bit10.64.9.118 - - [03/Jan/2014:17:24:34 +0200] "GET /api/datasets/e2132aef71b11dbf?data_type=data&chrom=chr&low=0&high=320487&mode=Auto&resolution=801.216067653277&hda_ldda=hda&filter_cols=%5B%22Score%22%5D HTTP/1.1" 200 - " http://ssb4:8082/visualization/trackster?dataset_id=e2132aef71b11dbf&hda_ldda=hda" "Mozilla/5.0 (Macintosh;
