%
% SPM (Statistical Parametric Mapping) is a package for the analysis
% functional brain mapping experiments. It is the in-house package of
% the Wellcome Department of Cognitive Neurology, and is available to
% the scientific community as copyright freeware under the terms of the
% GNU General Public Licence.
% 
% Theoretical, computational and other details of the package are
% available in SPM's "Help" facility. This can be launched from the
% main SPM Menu window using the "Help" button, or directly from the
% command line using the command `spm_help`.
%
% Details of this release are availiable via the "About SPM" help topic
% (file spm.man), accessible from the SPM splash screen.  (Or type
% `spm_help spm.man` in the MatLab command window)
% 
% This spm function initialises the default parameters, and displays a
% splash screen with buttons leading to the PET(SPECT) & fMRI
% modalities Alternatively, `spm('pet')` and `spm('fmri')`
% (equivalently `spm pet` and `spm mri`) lead directly to the respective
% modality interfaces.
%
% Once the modality is chosen, (and it can be toggled mid-session) the
% SPM user interface is displayed. This provides a constant visual
% environment in which data analysis is implemented. The layout has
% been designed to be simple and at the same time show all the
% facilities that are available. The interface consists of three
% windows: A menu window with pushbuttons for the SPM routines (each
% button has a 'CallBack' string which launches the appropriate
% function/script); A blank panel used for interaction with the user;
% And a graphics figure with various editing and print facilities (see
% spm_figure.m). (These windows are 'Tag'ged 'Menu', 'Interactive', and
% 'Graphics' respectively, and should be referred to by their tags
% rather than their figure numbers.)
%
% Further interaction with the user is (mainly) via questioning in the
% 'Interactive' window (managed by spm_input), and file selection
% (managed by spm_get). See the help on spm_input.m and spm_get.m for
% details on using these functions.
%
% If a "message of the day" file named spm_motd.man exists in the SPM
% directory (alongside spm.m) then it is displayed in the Graphics
% window on startup.
%
% Arguments to this routine (spm.m) lead to various setup facilities,
% mainly of use to SPM power users and programmers. See programmers
% FORMAT & help in the main body of spm.m

%
% FORMAT spm
% Defaults to spm('Welcome')
%
% FORMAT spm('Welcome')
% Clears command window, deletes all figures, prints welcome banner and
% splash screen, sets window defaults.
%
% FORMAT spm('AsciiWelcome')
% Prints ASCII welcome banner in MatLab command window.
%
% FORMAT spm('PET') spm('FMRI')
% Closes all windows and draws new Menu, Interactive, and Graphics
% windows for an SPM session. The buttons in the Menu window launch the
% main analysis routines.
%
% FORMAT Fmenu = spm('CreateMenuWin',Vis)
% Creates SPM menu window, 'Tag'ged 'Menu'
% F   - handle of figure created
% Vis - Visibility, 'on' or 'off'
%
% Finter = FORMAT spm('CreateIntWin',Vis)
% Creates an SPM Interactive window, 'Tag'ged 'Interactive'
% F   - handle of figure created
% Vis - Visibility, 'on' or 'off'
%
% FORMAT spm('ChMod',Modality)
% Changes modality of SPM: Currently SPM supports PET & MRI modalities,
% each of which have a slightly different Menu window and different
% defaults. This function switches to the specified modality, setting
% defaults and displaying the relevant buttons.
%
% FORMAT spm('defaults',Modality)
% Sets default global variables for the specified modality.
%
% FORMAT [Modality,ModNum]=spm('CheckModality',Modality)
% Checks the specified modality against those supported, returns
% upper(Modality) and the Modality number, it's position in the list of
% supported Modalities.
%
% FORMAT WS=spm('WinScale')
% Returns ratios of current display dimensions to that of a 1152 x 900
% Sun display. WS=[Xratio,Yratio,Xratio,Yratio]. Used for scaling other
% GUI elements.
% (Function duplicated in spm_figure.m, repeated to reduce inter-dependencies.)
%
% FORMAT [FS,sf] = spm('FontSize',FS)
% FORMAT [FS,sf] = spm('FontSizes',FS)
% Returns fontsizes FS scaled for the current display.
% FORMAT sf = spm('FontScale')
% Returns font scaling factor
% FS     - (vector of) Font sizes to scale [default [1:36]]
% sf     - font scaling factor (FS(out) = floor(FS(in)*sf)
%
% Rect = spm('WinSize',Win,raw)
% Returns sizes and positions for SPM windows.
% Win  - 'Menu', 'Interactive', 'Graphics', or '0'
%      -  Window whose position is required. Only first character is
%         examined. '0' returns size of root workspace.
% raw  - If specified, then positions are for a 1152 x 900 Sun display.
%        Otherwise the positions are scaled for the current display.
%
% FORMAT SPMdir=spm('Dir',Mfile)
% Returns the directory containing the version of spm in use,
% identified as the first in MATLABPATH containing the Mfile spm (this
% file) (or Mfile if specified).
%
% FORMAT [v,c]=spm('Ver',Mfile,ReDo,Cache,Con)
% Returns the current version (v) & copyright notice, extracted from
% the top line of the Contents.m file in the directory containing the
% currently used file Mfile (defaults on omission or empty to 'spm').
% %-The version and copyright information are saved in a global
% variable called [upper(spm_str_manip(Mfile,'rt')),'_VER'], as a
% structure with fields 'v' and 'c'. This enables repeat use without
% recomputation.
%-If Con [default (missing or empty) 1] is false, then the version
% information is extracted from Mfile itself, rather than the
% Contents.m file in the same directory. When using a Contents.m file,
% the first line is read. For other files, the second line (the H1 help
% line) is used. This is for consistency with MatLab's ver and help
% commands respectively. (This functionality enables toolboxes to be
% identified by a function rather than a Contents.m file, allowing
% installation in a directory which already has a Contents.m file.)
%-If Cache [default (missing or empty) 1] is true, then the version and
% copyright information cached in the global variable
% [upper(Mfile),'_VER'], as a structure with fields 'v' and 'c'. This
% enables repeat use without recomputation.
%-If ReDo [default (missing or empty) 0] is true, then the version and
% copyright information are recomputed (regardless of any stored global
% data).
%
% FORMAT xTB = spm('TBs')
% Identifies installed SPM toolboxes: SPM toolboxes are defined as the
% contents of sub-directories of fullfile(spm('Dir'),'toolbox') - the
% SPM toolbox installation directory. For SPM to pick a toolbox up,
% there must be a single mfile in the directory whose name ends with
% the toolbox directory name. (I.e. A toolbox called "test" would be in
% the "test" subdirectory of spm('Dir'), with a single file named
% *test.m.) This M-file is regarded as the launch file for the
% toolbox.
% xTB      - structure array containing toolbox definitions
% xTB.name - name of toolbox (taken as toolbox directory name)
% xTB.prog - launch program for toolbox
% xTB.dir  - toolbox directory
%
% FORMAT spm('TBlaunch',xTB,i)

% name1, name2,... - name strings of desired globals

% Returns MatLab version, truncated to major & minor revision numbers
%
% FORMAT spm('SetCmdWinLabel',WinStripe,IconLabel)
