GUI launching

I recently created a GUI and tested it and it worked fine. Returning to it a couple of weeks later when I try to run it, it doesnt run the opening function (im not sure if it runs it at all or partially) and this then leads to a load of errors e.g.

??? Attempt to reference field of non-structure array.

Error in ==> pfu_state_machine>PB_Reset_Callback at 309
set(handles.Txt_CBITRes,'String','Awaiting stimuli')

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> pfu_state_machine at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==> @(hObject,eventdata)pfu_state_machine('PB_Reset_Callback',hObject,eventdata,guidata(hObject))

??? Error while evaluating uicontrol Callback

However if I run the GUI from the GUIDE run GUI button or from the m file run button it behaves as it should. What has happened here?

All that has been done to the file in the interrim time is i made a copy of it to zip. Neither copy is working.

Please post, what "when I try to run it" exactly means. Do you double click on the FIG file? Or do you start the M-file? The singular in "I made a copy of *it*" sounds, like you did not copy the M- *and* the FIG file.

Hi Jan

I mean that when I try to run the fig from the matlab command line. I made a copy of the whole folder which the project resides in.

Thanks

You either must open your GUI file in a known directory for MATLAB, or must add your own GUI directory (folder address) to MATLAB search database! use path() statement and read its help.. good luck
