Hi again
I need the volume corresponding exactly to the ?h.white because I am doing
some tractography and my ROI are coming from the parcellation, so the
tractography mask should be the same than ?h.white. that's why I can not use
the aseg.
MRI-fill is more or less the same than imfill in matlab, isn't it? I was
looking for something that fill the volume from the mesh for mere accuracy..

Do you want everything in the white surface? That would include more than
WM.
If you want just WM, you can use the aseg.mgz, something like:
mri_binarize --i aseg.mgz --match 2 --match 41 --o wm.only.mgz
you may need a new copy of mri_binarize ...

Hello,
I need to convert the white matte surface to a volume :binary volume with
1
in white matter and 0 outside. I am using the mri_surf2vol command (on
both hemisphere), and fill it using matlab. Do you know if it is possible
to obtain the volume from the surface already filled ?
Thanks a lot.
Here is the command I use :
Mri_surf2vol --mkmask --hemi lh --template /my_image.img --volregidentity
mysubject --outvol outputvol_lh.img
