Hi Bruce,
I think I make it. I use the command like: mri_surf2vol --surfval subj/surf/rh.thickness --hemi rh --fillribbon --template subj/mri/orig.mgz --volregidentity subj/ --outvol subj/rh.ribbon.nii, and it works.
Last question on this is, once the surface file is changed into a volume file, how the file can be explained? In this case, I mean whether the brightness represents the cortical thickness, or the cortical itself in the image is drawn according to the thickness, so we can judge it directly from the image?
cheers, Kaiming

it's a surface overlay (so one value per vertex), not a volume. You will probably want to use mri_surf2vol to sample it into the volume if you want fsl to open it

Hi Bruce,
Yes I get the file rh.thickness.nii.gz, however it seems fs or fsl or imagej can not open it directly, should I add something?
cheers, Kaiming
