hi freesurfers,I wanted to know what is the difference between
'.aparc.a2009s.stats', '.aparc.DKTatlas.stats', '.aparc.pial.stats', and
'.aparc.stats' in the stats directory of freesurfer results?thanks,Yunus

Hi Yunus
The ones with “pial” in them are from the pial surface for things like
curvature and surface area, the ones without are from the white surface. The
rest of the name indicates which cortical parcellation the statistics are
summarized in (e.g. the lh.aparc.pial.stats contains statistics
What volume and what surface? You can recon-all the MNI152NLIN2009cAsym
to generate surfaces, then they will be in registration directly

Hi Freesurfers,
I was wondering if there is a registration matrix (from volumetric to
surface) for MNI152NLIN2
You are right that using all the scans will bias toward tp2. I think I
would just run the cross for each time point using all the data you
have. This will not bias the base because an average of the images
within each time point will be used to make the base. If possible, you
will want to make
No, sorry, that was only available in the old tksurfer/tkmedit. We have
not implemented it in freeview.

You should load
$chronic_CMI_volume_path/"$sub_base"_chronic-CMI_4-1.nii.gz into
freeview with the surfaces, eg
cd subject/mri
freeview nu.mgz
$chronic_CMI_volume_path/"$sub_base"_chronic-CMI_4-1.nii.gz -f
../surfs/?h.white ../surfs/?h.pial
and see if the lesion maps between the white and pia
sorry, what is the dura flag you are talking about? Also, dura generally
interferes with the placement of the pial surface, not the white (ie,
white-gray boundary) surface.

Not sure what you mean by the background. You can try binarizing the
electrodes (mri_binarize), then load it as a segmentation.

tksurfer was deprecated years ago, though it's replacement (freeview)
does not seem to have that capability either.

We usually use the white surface because its placement is independent of
the placement of the pial surface (and so independent of thickness and
volume), but it is really an empirical question.

Have you tried using the "intermediate" option (--int) in bbregister?
The intermediate volume should be a whole brain volume and it should
share a RAS space with the slab volume (eg, if they were acquired in the
same session; load both the slab and the intermediate in freeview to see
if they ar
Yes, that is correct.

I think that will work, but there are better tools for this kind of
thing. If you have 7.4, you can use mri_binarize, like
mri_binarize -dilate-vertex vno surf radius outmask
where vno is the center vertex, surf is the surface (eg, white), radius
is the desired radius of the cicrle, and outmask
Try using DOSS (--fsgd your.fsgd doss) instead of DODS (which is the
