I am trying to use guide and could use some help with functions in 2014a

I have a function "imgImport" which passes these output "im, hdr,old, datafile, hdrfile" but I can not grab this data in the next function. I noticed it is not propagating the data to the work space, and found that it is stored in the GUI. I have two buttons one to grab the image the second to crop the image; here is the function as I tried.

function pushbutton1_Callback(hObject, eventdata, handles)
%disp('imgImport')    
[im, hdr,old, datafile, hdrfile]= imgImport;

% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)

[imgVIS, imgSWIR, rect,img,rowend, rowstart, colend, colstart]=  cropping(im, hdr);
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

How do I get one button to grab outputs from the other buttons data.

You can use the handles structure with the guidata function to store/save user data to the structure. Try something like this

 function pushbutton1_Callback(hObject, eventdata, handles)

 % call your script
 [im, hdr,old, datafile, hdrfile]= imgImport;

 % assign the user data to the structure
 handles.im  = im;
 handles.hdr = hdr;

 % save the data
 guidata(hObject,handles);

Now in your other button callback, just access the data directly from the handles structure:

 function pushbutton2_Callback(hObject, eventdata, handles)

 [imgVIS, imgSWIR, rect,img,rowend, rowstart, colend, colstart] = …
     cropping(handles.im, handles.hdr);

Try the above and see if that does what you wish.

That worked, thank you much
