function Users = get_user_directory;
%GET_USER_DIRECTORY - Get the user's root directory information
% function Users = get_user_directory;
% User = get_user_directory;
% Accesses the Preferences to get the current Users structure and
% CurrentData, as a subfield fo Users, e.g. Users.CurrentData.
%
% Every attempt to get the current user database should call this mfile, which will in
% in turn call database_manager only if there is a problem.
%
% LOGIC: if the user has an active BrainStorm session running, then the structure
% will be found in the BrainStormTaskbar as application data BrainStormDataBase.
% If there is something wrong with that information, send the user to the data manager
%
% If the BrainStormTaskbar is not running, then we may be in batch mode, so get
% the information from the BrainStorm preferences. Send error messages to the
% standard output.
%
% Returns the structure with fields:
% Comment, string commenting on the location of the files
% STUDIES, string giving the root location of all studies
% SUBJECTS, string giving the root for subjects.
% FILELIST, structure, result of browse_study_folder(SUBJECTS)
% CurrentData with fields and examples:
% StudyFile: 'jcm_spont08-31.ds\jcm_brainstormstudy.mat'
% SubjectFile: 'jcm_mri\jcm_brainstormsubject.mat'
%
% Idea is that we then call load(fullfile(User.STUDIES,<filename>));
% i.e. all filenames are referential to a root.

% Date of creation: January 1999
% Date of modification: September 2001
%----------------------------------------------------------------------------------
% JCM 11/9/99 appended filesep if missing
% JCM 10/25/00 changed to use get_user_directory
% SB 11/13/00 Added an error message to force the user to move Users.mat into
% custom if necessary.
% SB 09/03/01 USer guidata to look for User information
% JCM 22-Mar-2002 allowing for get_user_directory to load from bst_prev_session
% JCM 28-May-2002 database_manager has replaced initialize_users, database_manager now
% uses getprefs rather than users.mat. Altered help block above to
% reflect new changes. Used try, catch to handle errors
% SB 03-Sep-2002 Return [] when database is not loaded properly
% JCM 30-Oct-2002 Strict enforcement of Preferences only, all other use disabled.
% Since startup sets a default if needed, errors should be minimal.
% JCM 20-Aug-2003 empty CurrentData default if necessary
% JCM 5-Sep-2003 Added FILELIST generation if it is missing from the database
