Hello Shaun, The documentaiton / help systems for Galaxy's new dataset libraries are under development , so we apologize for the lack of information at the current time - informative help is coming soon though. SHAUN WEBB wrote: You currently must be an "admin" user in order to create a new library. Admin users are currently configured in the universe_wsgi.ini file, something like this: # This should be a comma-separated list of valid Galaxy users admin_users = swebb1@staffmail.ed.ac.uk,any_other_galaxy_user@email.ac.uk When you login as an admin user, you an "Admin" link will be displayed in the top menu bar which points to the Galaxy admin interface. The Admin subsystem consists of many new features, including the ability to add new dataset libraries. When an admin user creates a dataset library, they should immediately assign permissions on the library before any new dataset or folders are added to the library. These same permissions will be inherited by all datasets and folders in the library. However, the admin can change these inherited permissions on newly added datasets and folders. Permissions on a folder can be different than the permissions on the Library or a parent folder. Any *new" datasets added to a folder will inherit the folder's permissions, but if the permissions on a folder are changed *after* datasets have been added to the folder, those new folder permissions will currently not override the existing permissions on the folder's contained datasets. The ability to do this will be added in the future. Permissions on libraries and datasets are fairly fine-grained. They can be associated with a single user or a groups of users that are associated with a role. When permissions ( that are associated with a role ) are set for a library item ( library, folder, dataset ), any user that has that role will be able to access the dataset from the Libraries menu item, but users that do not have that role will be restricted from seeing the library item. More details about how this works are included in the main Admin page. After looking at the Admin interface, let us know if you have any further questions. Thanks Shaun, Greg Von Kuster Galaxy Development Team
