Problem with deleting first images

Dear reader,

I know a similar problem has been reported before, but somehow the solution offered does not work for me.
And parts of the answer was in Chinese so I was not able to follow it completely.

DPARSF nicely starts with processing the DICOM files.
I get a folder called FunImg > Subject > XXX.nii.gz (containing a .nii with 207 images)
But then the following error message appears

??? Error using ==> delete

Not enough input arguments.

Error in ==> DPARSF_run at 276

            delete(DirImg(j).name);

Error in ==> DPARSF>pushbuttonRun_Callback at 935

    [Error]=DPARSF_run(handles.Cfg);

Error in ==> gui_mainfcn at 75

        feval(varargin{:});

Error in ==> DPARSF at 39

    gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating uicontrol Callback.

:

When DPARSF tries to delete the first images.
I am sure that I indeed have 207 images!
When I skip the Deletion of the first images I also get an error message.

I am running MATLAB on Windows 7. I Tried MATLAB 7.0 and MATLAB R2006a both with the same error occuring.
I am using the DPARSF_V1.0_100510 and REST_V1.4_100426 (though REST_V1.3... gives the same error message).

What could be the problem?
I would very much appreciate your help.

Best wishes,
Simone
