I analysis the volume of grey matter, and MNI152 as the mask of whole brain. Thanks!

And what is the data you analyzed in spm? You could use the mni space mask but it won't be very accurate.

Hi Bruce
I use the SPM to analysis my data, and use the xjview to get a mask (have .img and .hdr files) as ROI, use the MNI space in SPM analysis. Following I want to obtain the cortical thickness from this mask in Freesurfer, and I have analyzed all my individual subjects in FreeSurfer(recon-all). thanks!
