It is implemented, but I'm just not sure of the results. My results differ from those of Don Hagler from UCSD, and I'd like to track down the discrpancy before releasing it. You can always use the simlation approach (monte carlo or permutation). Use the --sim option to mri_glmfit followed mri_surfcluster with the --csd option. See --help on both of them and/or the wiki for more details. It takes longer but inevitably more accurate.

Hello all

I have computed and smoothed some thickness maps using Freesurfer. Next I would like to make inference using Gaussian Random Field theory (GRFT). How can I do it in Freesurfer? If it is not implemented in freesurfer , is there any thing that I have to take into account when applying any GRFT implementation to the statistical parametric thickness maps resulting from Freesurfer analysis?

In advance thank you
