Dear surfers,
I computed F-contrast using selxavg3-sess with an identity matrix as a contrast matrix. My question is about the result file “sig.*”. As far as I understand, the “sig.*” file contains signed-minnus-log-p-values (like, -log10(p)*Sign(t)) for a certain contrast.
So I expected the dimension should be #vertices-by-1, but the sig.* file is in the dimension of #vertices-by-1-by-1-by-#regressors. I would appreciate post-hoc tests after F-test, but the dimension doesn’t look like one… or is it? like i-th regressor v.s. (N-i) regressors? If one can tell where I can find p-values for the F-test, and what are the values in the sig.* file.
+ wait. is "fsig.*” for the F-test? and “sig.*” for a set of one-vs.-the-others contrasts? I would still appreciate if one can confirm it.
Best regards,
