Hi Doug,
Thanks very much for your reply.
The mri_vol2surf command line i used is:
mri_vol2surf --mov brainmask.nii.gz --reg bbregister.dof6.dat --trgsubject
fsaverage --interp trilin --projfrac 0.5 --hemi ${hemi} --o
brainmask.fsaverage.${hemi}.nii.gz --noreshape --cortex --surfreg sphere.reg
The mri_surf2surf command line i used is:
mri_surf2surf --srcsubject fsaverage --sval brainmask.fsaverage.${hemi}.nii.gz
--hemi ${hemi} --cortex --trgsubject fsaverage5 --tval
brainmask.fsaverage5.${hemi}.nii.gz --surfreg sphere.reg
Thanks!
Best!

Hi dong, sorry for the delay. What is your mri_vol2surf command line?

Dear Freesurfer experts,
I have a binary brainmask made in volumetric space and trying to transfer it
into surface space, first I use mri_vol2surf to transfer the mask into
fsaverage space, then run mri_surf2surf (fs 6.0) to down sample it to
fsaverage5 space.
After vol2surf, some values on the vertex in fsaverage space would be less than
1 due to the interpolation, however, I find values on these vertexes (<1 in
fsaverage) come to be 0 after mri_surf2surf in faverage5 space.
it doesn't happen in version 5.3, how can I solve this in 6.0?
Many thanks,
Dong Haoming
