Hi, sorry to bother but now it's the 3rd time I get a message saying that if the problem persists I should contact the galaxy staff. It occurs while running cuffcompare of total RNA to a genomic reference that I uploaded myself (Sulfolobus acidocaldarius). It's about MPI processes terminated incorrectly if I understood it correctly. Just to let you know... These are the details of the generated error: --------------------------------------------------------------- user username twincacca quota_percent 32 total_disk_usage 86918246471 nice_total_disk_usage 80.9 GB email antoine.buetti@lnu.se is_admin false tags_used model_class User id 3e934cb0877d45db source HDACollection(8fb8cc6fa23b1dbe,99) xhr readyState 4 responseText {"err_msg": "Uncaught exception in exposed API method:", "err_code": 0} responseJSON err_msg Uncaught exception in exposed API method: err_code 0 status 500 statusText Internal Server Error responseHeaders Server nginx/1.4.7 Date Fri, 16 May 2014 08:58:57 GMT Content-Type application/json Transfer-Encoding chunked Connection keep-alive Cache-Control max-age=0,no-cache,no-store options data parse true emulateHTTP false emulateJSON false ---------------------------------------------------------------END
