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
