Hello I've encountered an error when creating the first data library within a Galaxy installation. The data library appears to be created but an error message appears ("Error attempting to display contents of library (Test Data): No module named controllers.library_common" - see attached screenshot) and although the library name appears, it's not possible to interact further with the library e.g. to add datasets. The original error occurred on our nascent production setup, but I can reproduce it on a brand new vanilla local galaxy instance (changeset 7828:b5bda7a5c345) with the only configuration being to register as a user and set the "admin_users" parameter in universe_wsgi.ini. Then, go to "admin" -> "manage data libraries" -> "create new data library". This error doesn't appear when creating a new data library on an instance which already has existing libraries, and debug output doesn't give me any additional clues about where the "missing module" is coming from. I don't think this problem has been reported previously however apologies if it's already been addressed on the mailing list. Thanks for any help Best wishes, Peter -- Peter Briggs peter.briggs@manchester.ac.uk Bioinformatics Core Facility University of Manchester B.1083 Michael Smith Bldg Tel: (0161) 2751482
