Issue with DPARSF concering preprocessing

Good morning,

I am an intern at Ghent University and I am trying to use DPARSF to preprocess my data. Actually, they have already been preprocessed by my colleague, but they still need to undergo some further steps (detrending, filtering, ...). I downloaded DPABI and DPARSF on my computer, I set the paths (I added DPABI and DPARSF with subfolders on Matlab), I loaded my participants and I set all the parameters on DPARSF, but when I tried to run it, it was giving me this error:

Undefined function 'gcp' for input arguments of type 'char'.
Error in DPARSFA_run (line 1461)
if isempty(gcp('nocreate')) && Cfg.ParallelWorkersNumber~=0
Error in DPARSF_run (line 113)
[Error] = DPARSFA_run(Cfg);
Error in DPARSF>pushbuttonRun_Callback (line 1154)
    [Error]=DPARSF_run(handles.Cfg);
Error in gui_mainfcn (line 96)
        feval(varargin{:});
Error in DPARSF (line 52)
    gui_mainfcn(gui_State, varargin{:});
Error while evaluating uicontrol Callback

Also, I had many problem by trying to use the PreprocessedDemoData on my computer - by using DPARSF and DPABI and by loading the .mat file you suggested on this website ("DPARSF_Preprocess_ALFF_FC.mat") - to calculate ALFF/fALFF/Functional Connectivity. I attached a picture in which you can see the Matlab error.

I have Matlab 2013a, DPABI 4.0, REST 1.8 and SPM12. Might these errors concern an issue with compatibility?

Thank you for your time, I look forward to hearing from you soon.

Kind regards,

Letizia
