Error with standardization tool and image calculater when trying to z-standardise

Hello,

I was playing a little bit with the standardization tool and wanted to z-standardize some nifti files I created. I got the following error:

Standardizing...

Writing to files...
Attempted to access TempIndex(0); index must be a positive integer or logical.

Error in y_Standardization (line 219)
    [status,message,messageid] = mkdir(fullfile(OutputDir,[Path(TempIndex(end)+1:end),Suffix]));

Error in DPABI_Standardization>ComputeButton_Callback (line 213)
[StandardizedBrain, Header] = y_Standardization(ImgCells, MaskFile, MethodType, OutputDir, Suffix);

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error while evaluating uicontrol Callback

I tried it with some unstandardized ReHo images from the preprocessing, but get the same error.

Then I tried to use the Image calculator to z-standardise the images. I loaded all the images on the left side as g1 and the single images on the right side. I used the formular specified in the help: (i1-mean(g1))./std(g1). Then I got the following error.

Error using fprintf
Function is not defined for 'cell' inputs.

    fprintf('%s: %s\n', GroupLabel{j}, GroupCells{j});

Any idea, what the problem might be? I'm using spm12

Thanks in advance :)
