cannot find subjects

 Dear all,
I have a problem loading into DPARSF A (v2.3) those subject folders that include already preprocessed 4D RS fMRI files.
The folder structure is 
Rest
FunImg
Subj_001
    detrend_4DVolume.nii
Subj_002
     detrend_4DVolume.nii

The images are the output of a previous REST preprocessing including motion correction, CSF/WM signal, fltering, detrending and smoothing. I like to perform a FC analysis with the DPARSF A on these images.
The subject folders are not recognized, however. Changing the name of the FunImg directory (e.g. to FunImgAWRSDF) does not work either.
Also clicking on the participant box does not open a dialog window to select manually subject folders (as shown in the multidmedia presentation on DPARSF A).
We use an Apple OS X (v 10.8.3) operating platform.

Any suggestions are welcome.

With best regards,
Michael
