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. https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2007-September/006199.html https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2007-September/006112.html Thank you in advance, Xin
