Hi Lara
Can you send us some pictures? The answer depends on why

Hi everyone,
Very quick question - I need to shrink the white matter surface in a very
specific (constrained) region. Can you please confirm that the right way to go
about this

Hi Mike
sorry, I never really documented it. Essentially they provide limits on
the allowable intensities of the various tissue classes at the different
boundaries (gray/white and pial). Unless those constraints are satisfied it
will not try to place the boundary in that region

Have a look at mris_make_surfaces.c, this is how I learned about most of
this stuff as the code is pretty well commented (and Bruce telling me
things).
Peace,
Matt.

Hi Bruce,
I was wondering if there is info somewhere about what each of those 7 MIN_
and MAX_ variables control regarding the positioning of the white and pial
surfaces?
thanks,

Hi Andrea
what is the background image? This is usually either a failure of the
intensity normalization or of the surface deformation/segmentation to
adaptively estimate the underlying intensity distributions of the
gray/white matter. If you look in recon-all.log for that subject you will

Dear Freesurfers,
After running recon-all, the wm surfaces are too close to the pial surface,
some gray matter is segmented as white matter as seen in the attached
picture (red cross: a bigger cortical part is included in the white matter).
How can I shrink the wm surface?
Thank you for your he
