gui_cnt_open

PURPOSE ^

gui_cnt_open - Load a CNT data file into matlab workspace

SYNOPSIS ^

function [p] = gui_cnt_open(p,command,parent)

DESCRIPTION ^

 gui_cnt_open - Load a CNT data file into matlab workspace
 
 Usage: [p] = gui_cnt_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.

 This function returns values into p.cnt
