I have another question. To view the thickness map, we first load a surface of the corresponding subject (i.e. ?h.inflated) and then overlap the thickness map on it. So to view the mean thickness map, do I also need to average the volumes/surfaces of the subjects?

Hi Xiaojing,

mris_average_curvature will do it, and I think Doug has some other tools that will as well.

cheers,
Bruce

Hi,

I have a question regarding how to average cortical thickness maps.

I have a dataset with 10 MR brain images and I've run recon-all on each
of them. So I've got thickness maps ?h.thickness for each subject. I wonder
whether freesurfer provides a tool that can average the cortical thickness
maps
over the dataset.

Thanks.

Best,

Xiaojing
