MATLAB GUI callback to open a new figure?

Hello. I am trying to run a GUI program which opens when I run the source script file. When the script is run, a window opens with a pushbutton inside of it. When the user clicks on the pushbutton I want this window to close and a new one to open (or even better, the new window should replace the old one at the exact location on the screen). The next screen will also be a figure with its own set of pushbuttons and callbacks etc. I have figured out how to close the figure when the pushbutton is clicked by entering the required commands in the callback. However I can't seem to open a new figure. It leads to a destroyedcallback error and also says that the figure I tried to open didn't exist (although it does exist in the same location as the source script file). The pushbutton for the main window looks like this:

   % --- Executes on button press in prob1push.
function prob1push_Callback(hObject, eventdata, handles)
% hObject    handle to prob1push (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
  h_help = findobj('Tag','prob1push');
   if (isempty(h_help))
      % Do something here -- window doesn't currently exist
   else

      closereq;

   end

Rahul - just call the name of the second GUI. i.e. if the name of the other GUI is OtherGUI, then just call it as

 hGui = OtherGui('Visible','off');

to open it but keep it invisible. You can then use hGUI to change the position of the GUI and then make it re-appear.

 set(hGui,'Position',[x y w h]);
 set(hGui,'Visible', 'on');

where `[x y u v]` is the new position (and dimensions) of the GUI.

Is this call to the other GUI supposed to be inside the pushbackbutton callback function?
