It should work. How are you smoothing the thickness file? You need to smooth it in the native surface space.

Dear all

I would like to look at the change in the average values of thickness after smoothing. But mris_anatomical_stats does not work on the smoothed files as the no of vertices of the annot files and the smoothed files are very different.

I tried recreating annot files using the flag -surf pial and the aparc+aseg.mgz but I got following error message: could not open translation file /Applications/freesurfer/cma_parcellation_colors.txt could not open translation file /Applications/freesurfer/Simple_surface_labels2002.txt

Your help would be appreciated. Thanks in advance Raka
