Chaogan,
I am sorry to distrub you again.
WHEN I am perfroming the two sample t-test, errors jumped out. I am not familiar with MATLAB, thus, this frustrated me a lot.

I guess, the problem lies on the mask dimensions are not consistently.

but, i don't know how to resample the mask in REST.

Sorry for my dummy quesitons on MATLAB.

Hi,
"Undefined function 'fcdf'"
means you didn't install Statistical Analysis Toolbox. Please install it for MATLAB.

Best,
