Hi Cirong,

I took a look at your model and it matched the one I succesfully used. The only difference is that your contrast (which is not used anyway) is empty. That might prevent the model from running successfully. Just set EV1 to 1 in the global contrast and see it that solves it. With the empty contrast, feat fails to make the design matrix and other needed files for the analyses.

Tested it here with my model. It fails if I make the contrast empty like yours. So if you set that contrast correctly it should hopefully  work. Otherwise we're missing something else.
