Hello,

I was wondering if someone can please assist with viewing the results of a paired t-test. The results look off in the sense that connectivity shows in regions like the ventricles, cerebellum, and even outside the brain. Is this correct?

Please see the screenshots of the results attached (includes paired t-test and paired t-test with clustsim).

Please see the script I am running below:

I've tried the above script with "" before and after the data file names but getting the same result. Any advice or suggestions you can provide would be greatly appreciated!

Thanks so much!
