function [p] = gui_mri_open(p,mri_open_command,parent)

% GUI_MRI_OPEN - Load & Display an Analyze volume
% 
% Useage: [p] = gui_mri_open(p,[command],[parent])
% 
% p is a structure, generated by 'eeg_toolbox_defaults'
% command is either 'init' or 'load'
% parent is a handle to the gui that calls this gui, useful
% for updating the UserData field of the parent from this gui.
% The p structure is returned to the parent when the parent 
% handle is given.
