Hello All, I am facing an issue with uigetfile. What I have is a button "Upload" along with a edit box which supposed to be showing the path of the uploaded file. Here is what I tried:

   %--- Executes on button press in upload.
    function upload_Callback(hObject, eventdata, handles)
    % hObject    handle to upload (see GCBO)
    % eventdata  reserved - to be defined in a future version of MATLAB
    % handles    structure with handles and user data (see GUIDATA)
    [FileName1,PathName1] = uigetfile({'*.txt';'*.csv';'*.*'},'Select the text file that contains the data');
    if isempty(FileName1)
        errordlg('No file was selected that contains the data so the calculation was aborted.');
        flag = true;
        return
    end
    % text file should consist of two columns, 
    fid = fopen(fullfile(PathName1,FileName1));
    if fid == -1
        errordlg('The file selected could not be read so the calculation was aborted.');
        flag = true;
        return
    end
    d = textscan(fid,'%f %f');
    fclose(fid);
    S3.fValues = d{1} % data1
    S3.rValues = d{2} % data2
    S3.selected_dir_upload =[Pathname1,FileName1];
    handles.S3.selected_dir_upload =S3.selected_dir_upload  ;
    guidata(hObject, handles);
    set(handles.upload_edit, 'String', S3.selected_dir_upload)
    set(handles.upload, 'UserData', S3);

I am not able to set the path in edit box. Your help is much appreciated.
