gui_elec_open

 gui_elec_open - Load an electrode data file into matlab workspace
 
 Usage: [p] = gui_elec_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.
