Also, p-values for t-tests are two-sided.

Jeff,
sig.mgh actually stores the -log10(p), not p, so to get the true p-value
of say, -2 (in the sig.mgh), take 10^-2 (giving you the true p-value of
0.01).

Hello Surfers,
I am trying to verify the p-value sig.mgh maps outputted from the mri_glmfit
command as the first part of a more advanced analysis. We have been extracting
the thickness data for a single vertex from each of our 58 subjects in two
control groups and then running a significiance
