Acessing imrect with another callback

I have already created a dragable box using imrect and need to use another callback in expanding it. Please , I need a clue. I have tried the code code attached.

But I am getting the error below:

Error in CellAnalysis>button_process_Callback (line 135)

api = iptgetapi(h);

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in CellAnalysis (line 42)

gui_mainfcn(gui_State, varargin{:});

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)CellAnalysis('button_process_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.
