In theory it is because the F can be converted to a p which can be
converted into a pseudo-z. When you run mri_glmfit-sim, you should make
sure to use an unsigned test ("abs")

Hi Freesurfer experts.
Does mri_glmfit-sim Monte-Carlo cluster size correction is also usable
for F-test?
The doc says that it synthesizes a z map (I assume from a normal
distribution) for computing the voxel-wise thresholds and cluster size
distribution.
Maybe I am wrong with my stats but I wonder if it is ok to use this
null-hypothesis to a F-distributed data such as results from a F-test.
Thanks!
