Dear fs/fsfast user:
Would you please tell me how to do F test in fsfast? For example, I have 4 conditions, and want to test the 4x4 contrast matrix [1 0 0 0; 0 1 0 0; 0 0 1 0;0 0 0 1] with a F test. How should I use mkcontrast-sess or other commands to construct the contrast matrix and do F test?

Thanks in advance.
