Error in functional connectivity analysis when using DPARSF or REST

Hello, Dear DPARSF team

I ran into some problems when I try to compute functional connectivity when using DPARSF. It gave me error message as following. I tried REST to do FC analysis and got same error message. And it is apparently not due to different preprocessing because I used DPARSF to do the preprocessing. Would you please help me solve the problem? Thanks a lot for your help in advance.

The wired thing is when I define ROI by using /DPARSF_V1.0_100510/Templates/BrainMask.img, CsfMask.img and WhiteMask.img. DPARSF can do The FC analysis successfully. But of course, the results are meaningless for us because they are not real ROI. Can anyone please tell me how to make some useful ROI mask. Thanks a lot.
