Hi, thanks for the answer. Sorry for my delayed response.
I tried the mris_calc command, but it didn't work. Here's the error
message I got:
"mris_calc: curvature file 'lobe.mgz' has wrong magic number."
The multiplication was easily done i Matlab, but is there any way to do
this with FreeSurfe
The 2nd step only creates a mask of the entire surface. You need a step
3 in which you multiply them together:
3. mris_calc -o product.mgz lobe.mgz mul lobe_surface.mgz

I tried this, but something is going wrong. Here's what I did:
1. I ran $ mri_binarize --i subjid/mri/aparc+asec.mgz --match xx --match
yy --o lobe.mgz
- this produces a nice binary mask of, say, the left frontal lobe.
2. Then I ran $ mri_surf2vol --mkmask --surf pial --hemi lh --template
lobe.mg
Use mri_surf2vol to create volumes. You can binarize aparc+aseg.mgz to
give a mask of an area (use --match), then take the intersection of the
mask with the surface-in-volume.

Hi,
I'm working on a fractal dimension analysis of the pial- and
white-matter surface. The matlab script that calculates the fractal
dimension needs binary nifti-files as input. Since FreeSurfer creates
the surfaces I need, here's what I want to do:
I'd like to convert the pial and white-matter
