Load the fsaverage surface in tksurfer (say lh.inflated) then load the patch we
distribute with fsaverage (I think it's called something like
lh.cortex.patch.flat) with file->load patch. Then load whatever overlay you
want in the same way you would on the inflated surface

Hi Doug,
Thanks for your suggestion on tksurfer, it works.
I would like to map all the subjects into a flat map because I am curious about
the 2-D thickness patterns between different groups. I think there will be some
distinctions.
But if I flatten fsaverage, how can I map everyone?s 3D surfac
It sounds like you just want to do a standard group analysis. Look in
the wiki for instructions and tutorials. Basically, you use mris_preproc
to create a stack of your subjects thickenss maps, then use
mri_surf2surf to smooth, then mri_glmfit to do the group analysis

Hi Qiongmin
1) The command you ran resamples the thickness from being a scalar field
over the subject surface to being a scalar field over the fsaverage
surface. If you load fsaverage (say inflated) in tksurfer or freeview you
should then be able to load the overlay onto it.
2) We provide pr
Dear Doug and all,
I have already done two things:
(1) 'recon-all’ to the segmentation for 140 subjects;
(2) surface registration to fsaverage template for 1 subject using:
mri_surf2surf --hemi lh --srcsubject sub001 --srcsurfval thickness --src_type
curv --trgsubject fsaverage --trgsurfval ./su
