You are right, Doug. The number of zero-value vertices got reduced more and more when I increased the smoothing kernel size.
Thanks a lot for your help! -Glen

command looks ok. Just using a slab would create 0s in a lot of places, but those 0s should get smoothed with other non 0s

Does the cortex label have any holes in it and do the holes in your output correspond? Try it with out the --cortex flag. doug -> there was some improvement when I did smoothing after removed '-- cortex flag', such that the number of vertex with '0' was decreased from 35785 to 21898.I piped in a slab EPI image (covering only temporal regions) to the freesurfer using mri_vol2surf function (see below for more details). I'm guessing this has caused some holes (i.e., zero-value vertices) in labels during 2D reconstruction? Or alternatively, do you see any problem in the command below?
mri_vol2surf --src ' Functional_dir Subj '/FUNCTIONAL/rabold' num2str(run) zero_digit num2str(TR) '.nii' ... ' --srcreg ~/DMPC/3D/data/' Subj '/ANATOMY_SPM/FS-register.dat --hemi rh --projfrac 0.5 --noreshape --o ~/DMPC/2D/data/' Subj '/MGH/rabold' num2str(run) zero_digit num2str(TR) '_R.mgh'];
