DPARSFA error message

Hi, dear REST guru

I got an error message while running DPARSFA. Could you please help?

??? Index exceeds matrix dimensions.

Error in ==> DPARSFA_run at 194
delete(DirImg(j).name);

Error in ==> DPARSFA>pushbuttonRun_Callback at 969
[Error]=DPARSFA_run(handles.Cfg);

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

Error in ==> DPARSFA at 30
gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback

Thank you,
