i have two buttons to search different directories but the second button cant add more variables to the guidata

function pushbutton5_Callback(hObject, eventdata, handles)

    symbol=char(92);
    dirControl = uigetdir;
    dirControl= strcat(dirControl,symbol);
    controlfiles=dir([dirControl '*.img']);

        for i = 1:numel(controlfiles)
        file= strcat(dirControl,controlfiles(i).name,',1');
        imcell{1,1} =(file);
        end

        handles.imcellG1=imcell;
        handles.DirectorioG1=dirControl;
        guidata(hObject, handles)

function pushbutton6_Callback(hObject, eventdata, handles)

     symbol=char(92);
    dirControl = uigetdir;
    dirControl= strcat(dirControl,symbol);
    controlfiles=dir([dirControl '*.img']);

        for i = 1:numel(controlfiles)
        file= strcat(dirControl,controlfiles(i).name,',1');
        imcell{1,1} =(file);
        end

        handles.imcellG2=imcell;
        handles.DirectorioG2=dirControl;
        guidata(hObject, handles2)

the result is Undefined function or variable "imcell".

Answer 1

[Star Strider]

I didn’t run your code, but just from observation it seems that if ‘imcell’ has not been created, your ‘controlfiles’ array has zero elements. (Something about either assignment of ‘dirControl’ is probably not correct.) The loop is not iterating.

[steven Garcia]

yes you right my files in the second directory are wrong

It is my pleasure to help!

Answer 2

[Geoff Hayes]

Steven - in your second callback, look closely at the guidata call

 guidata(hObject, handles2)

The second parameter is named handles2 whereas all of your code is updating handles. (I'm surprised that an error isn't thrown because of the invalid variable name.) Just change this line to

 guidata(hObject, handles);

and try again.
