Hi,

You can find R-fMRI measures under the Results folder. Just organize them into 3 folders according to their group assignment, and you can perform the ANOVA analysis.

do a anova for three groups, use the viewer to view the F contrast. some areas are significantly activated. what does it mean, or how to explain this?

Significant F value indicates there is difference exists at least between one pair of groups.

so it likes the analysis  of the behavioral data. when the F value is significant, then do the post T test between two variables?

That's OK.

In DPABI->Statistical Analysis->ANCOVA,

You can perform several kinds of post-hoc tests:

preprocessing problem with the newest version of DPABI, the normalization can't done, i thy 2 times. so i change back to the old version. it didn't show error.  why?

By the way, when I do the T test, i chose the mask file-->AllResampled_BrainMask_05_91x109x91. if the mask file is right?
