Hi Alfonso,
Thank you! I have been downloading the latest version.
I think that I have found the reason. In the SETUP--ROIs tab, the dimensions of White matter and CSF had been 16 (default I think), while after I tried to adjust them to 6, it run well. I did not notice the dimensions before. The dimensions of WM and CSF are supposed to be used for CompCor, is it? I see that in the PREPROCESSING step, the default dimensions of confounds WM and CSF are 5, what number of  dimensions should be set in the SETUP?

Cheers,
Xinyuan
