Hello, I'm trying to create a custom visualization in Trackster. I am doing the following steps. Visualization -> New Visualization -> Add a Custom Build I get directed to the url below: http://galaxy.ca:8080/user/dbkeys?use_panels=True But the web page says: Server Error An error occurred. See the error logs for more information. (Turn debug on to display exception reports here) My paster.log file shows the following: WSGI Variables -------------- application: <paste.recursive.RecursiveMiddleware object at 0xf070d90> paste.cookies: (<SimpleCookie: __utma='99541067.1404064366.1320847925.1320847925.1320857512.2' galaxycommunitysession='eb142648ac45b770e95464ae1d51cc6457899dd48ca7f3e61a826ece0a2b5d2a65f4ac4aabb6e5e9' galaxyreportssession='c6ca0ddb55be603a922aa045b4afae662fca8487217f2ea25e5b488dcf5d52aefac5347681c8bf98' galaxysession='c6ca0ddb55be603a67ec94afb2c9a07cafdf91af0226f4689d096411ea1bc0c1004977df81ecca90' toolshedgalaxyurl='http://martin.dnalandmarks.ca:8080/'>, '__utma=99541067.1404064366.1320847925.1320847925.1320857512.2; galaxysession=c6ca0ddb55be603a67ec94afb2c9a07cafdf91af0226f4689d096411ea1bc0c1004977df81ecca90; galaxycommunitysession=eb142648ac45b770e95464ae1d51cc6457899dd48ca7f3e61a826ece0a2b5d2a65f4ac4aabb6e5e9; toolshedgalaxyurl="http://martin.dnalandmarks.ca:8080/"; galaxyreportssession=c6ca0ddb55be603a922aa045b4afae662fca8487217f2ea25e5b488dcf5d52aefac5347681c8bf98') paste.expected_exceptions: [<class 'paste.httpexceptions.HTTPException'>] paste.httpexceptions: <paste.httpexceptions.HTTPExceptionHandler object at 0xf0702d0> paste.httpserver.thread_pool: <paste.httpserver.ThreadPool object at 0x2ae44714c0d0> paste.parsed_querystring: ([('use_panels', 'True')], 'use_panels=True') paste.recursive.forward: <paste.recursive.Forwarder from /> paste.recursive.include: <paste.recursive.Includer from /> paste.recursive.include_app_iter: <paste.recursive.IncluderAppIter from /> paste.recursive.script_name: '' paste.throw_errors: True webob._parsed_query_vars: (MultiDict([('use_panels', 'True')]), 'use_panels=True') wsgi process: 'Multithreaded' ------------------------------------------------------------ Any help would be much appreciated.
