Useage: [mri] = mri_toolbox_defaults(command,[mri])
command = 'create'
'read'
'write' or 'write_other'
mri = structure returned by create|read command
structure to write for write command
All read and write commands are to a matlab .mat file. The
'write_other' command will write out a data specific archive
that can be accessed from the recent files list. It will be
located in the folder where the eeg data is opened.
Examples:
mri = mri_toolbox_defaults; % create new defaults
mri = mri_toolbox_defaults('read'); % read saved defaults
mri_toolbox_defaults('write',mri); % write current mri as default
mri_toolbox_defaults('write_other',mri); % write current mri data
The write command will write to the mri_toolbox
installation folder. The read command will first
try to find the paramater file in the mri_toolbox
installation and otherwise recreates the defaults.
Notes: Handles parameter structure for the
mri_toolbox routines.</pre></div><!-- crossreference --><h2><a name="_cross"></a>CROSS-REFERENCE INFORMATION <a href="#_top"><img alt="^" border="0" src="../up.png"></a></h2>This function calls:<ul style="list-style-image:url(../matlabicon.gif)"><li><a href="mri_toolbox_defaults.html" class="code" title="function [mri] = mri_toolbox_defaults(command,mri);">mri_toolbox_defaults</a> mri_toolbox_defaults - Create, read, write mri_toolbox defaults</li><li><a href="mri_toolbox_recent.html" class="code" title="function [ files, varargout ] = mri_toolbox_recent(filename,command);">mri_toolbox_recent</a> mri_toolbox_recent - Keep track of mri_toolbox .mat files</li></ul>This function is called by:<ul style="list-style-image:url(../matlabicon.gif)"><li><a href="gui_avw_open.html" class="code" title="function [mri] = gui_avw_open(mri,command,parent)">gui_avw_open</a> gui_avw_open - Load & Display Analyze 7.5 data</li><li><a href="gui_cor_open.html" class="code" title="function [mri] = gui_cor_open(mri,command,parent)">gui_cor_open</a> gui_cor_open - Load & Display FreeSurfer COR-??? data</li><li><a href="gui_ge_open.html" class="code" title="function [mri] = gui_ge_open(mri,command,parent)">gui_ge_open</a> gui_ge_open - Load & Display MRI data</li><li><a href="gui_mri_open.html" class="code" title="function [mri] = gui_mri_open(mri,command,parent)">gui_mri_open</a> gui_mri_open - Load & Display MRI data</li><li><a href="mri_open.html" class="code" title="function [mri] = mri_open(mri)">mri_open</a> mri_open - function to call various mri data tools</li><li><a href="mri_toolbox.html" class="code" title="function [ varargout ] = mri_toolbox(command)">mri_toolbox</a> mri_toolbox - Graphical user interface (GUI) to various MRI tools</li><li><a href="mri_toolbox_defaults.html" class="code" title="function [mri] = mri_toolbox_defaults(command,mri);">mri_toolbox_defaults</a> mri_toolbox_defaults - Create, read, write mri_toolbox defaults</li></ul><!-- crossreference --><h2><a name="_source"></a>SOURCE CODE <a href="#_top"><img alt="^" border="0" src="../up.png"></a></h2><div class="fragment"><pre>0001 <a name="_sub0" href="#_subfunctions" class="code">function [mri] = mri_toolbox_defaults(command,mri);</a>0002 0003 <span class="comment">% mri_toolbox_defaults - Create, read, write mri_toolbox defaults</span>0004 <span class="comment">%</span>0005 <span class="comment">% Useage: [mri] = mri_toolbox_defaults(command,[mri])</span>0006 <span class="comment">%</span>0007 <span class="comment">% command = 'create'</span>0008 <span class="comment">% 'read'</span>0009 <span class="comment">% 'write' or 'write_other'</span>0010 <span class="comment">% mri = structure returned by create|read command</span>0011 <span class="comment">% structure to write for write command</span>0012 <span class="comment">%</span>0013 <span class="comment">% All read and write commands are to a matlab .mat file.
