are you trying to do this for a single subject or for a group of subjects , or group average data? On Tue, 18 Jun 2013, xiangbo_2010 wrote:
my subject has finished the recon-all on the structural image, whether use the command: "mri_vol2surf --src sig.img --src_type analyze --srcreg register.dat --hemi rh --o ./sig-rh.img --out_type analyze --float2int round --trgsubject ico --icoorder 7" to obtain the result? thanks!

and what subject do you wan to obtain thickness measures from? You could use mri_vol2vol to map your mask to the individual using the MNI transform On Mon, 17 Jun 2013, xiangbo_2010 wrote:
the mask was obtained from xjview, and use the MNI space in my study, thanks! Bo

sorry, the formatting of your emails is lost in my reader and you may have said this before, but what is the mask of? What space is it in?

I want to get cortical thickness, and have finished the recon-all, and obtained the mask from SPM which include the file with .img and .hdr, whether I should convert the file (.img and .hdr) to file (.nii), and
use
the command: "bbregister --s bert --mov func.nii --init-spm --reg register.dat tkregister2 --mov func.nii --reg register.dat --surf " to obtain the result? thanks!
