I am trying to use the GUI environment to obtain data from the serial port. Ideally I would like to have a serial config file serparate from my main file with the toggle button callback and everything, but that has been giving me trouble.

So I am trying to do the serial config whent eh toggle button is pressed. So far when I run the program, the program plots the data coming into the serial port just fine, however when I stop the program by pressing the toggle button, I get these errors:

Error in ==> TEST>togglebutton1_Callback at 122
          Out5(i) = fread(s);  
Error in ==> gui_mainfcn at 96
          feval(varargin{:});
Error in ==> TEST at 45    
          gui_mainfcn(gui_State, varargin{:});
Error in ==>
@(hObject,eventdata)TEST('togglebutton1_Callback',hObject,eventdata,guidata(hObject))
??? Error while evaluating uicontrol Callback
