t = sign(gamma) * sqrt(F)
where gamma is the gamma.mgh volume.

Hello, Freesurfer group,
I need T values instead of F values for a one-sample T test GLM. How
can I convert the values in F.mgh or sig.mgh (for 12 subjects one
group no factor) to T values and overlay them on the surface?
I found the similar questions in the following emails posted on
freesurfer email list. I want to follow up these questions.
