Dear FreeSurfers,
I am interested in
sampling values in the superficial white matter (SWM)
region, which is an area of about 0.5mm below the GM/WM
boundary.
To extract values of
each vertex in that region, I have successfully used the
mri_vol2surf function with the projfrac option, such as
below:
mri_vol2surf --src
<src_img> --out <output mgh file> --out_type
mgh --hemi lh --projfrac -0.5 --regheader <recon-all
output> --surf white --interp trilinear
However, I would also
like to get surface type files (like lh.pial, lh.white, etc)
that I could overlay on Freeview for visualization purposes.
I see papers with
figures that have a visualization of surfaces below the
GM/WM boundary, but I am not sure how I can obtain this.
I would really
appreciate if anyone could give me any hints or suggestions
on how I could do the same.
Thanks in advance!
Best regards,
Kristine
