Hi Abel,
no, there's no automated tool for this without special purpose
acquistions. You'll need to edit the brainmask.mgz to remove the dura
that the pial surface is grabbing.
sorry :<

Hello,
I've been looking through the archives and still have some questions
about getting the best data for GM volume, WM volume, and the volumes of
each sub-cortical structure. This is lengthy, but I'm trying to save a
lot of future man-hours that I wasted on the first dataset I was doing.

Hello,
Will any of the FS utilities read a Siemens DICOM file and dump the
(complete) DICOM header information to the terminal or text file? I've
looked at the options for mri_info and unpacksdcmdir, but as far as I
can tell neither have this capability. We have a handy Sun executable

You can get the DCMTK to install and use its dcmdump utility.

mri_probedicom will dump a lot of stuff, but not everything. If you know
what you want, you can have it dump particular tags.

Hi Simon,
yes, you would need to skip the watershed step (it is our skull
stripping), or better yet, replace it with bet, since at some points we
need the skull on e.g. to do TIV estimation. Do you find our skullstripping
is failing? In our hands the current version is extremely robust - worki
Hi Binyam,
for cortical analysis it shouldn't be an issue. Subcortically the atlas
does consist of adults, but in our experience it only makes a difference
at younger ages than the ones you are imaging. We to provide tools for
building your own atlas if you are interested.

On T
Freesurfers,
I had a couple of questions regarding your atlas.
I'm working with a children and young adult subject population (ages 7-18). I'm
interested in anatomical measures such as cortical thickness, and volumes of
different structures. What are your thoughts on what atlas to use for thes
Hi,
I am having troubles getting the right options with mri_convert.
I ran:
recon-all -autorecon1 -i original.mnc -s subj1
recon-all -subcortseg -s subj1
I now want to convert aseg.mgz into aseg.mnc but in the same space and
with the same orientation as my original.mnc file.
My original.mnc file
Mishkin,
try this:
mri_vol2vol --mov aseg.mgz \
--targ original.mnc \
--o aseg-in-native.mnc \
--regheader \
--interp nearest

Dear FS experts
We analysed data with FS 4.0.1. In the past, when analyzed this data with FS
3.0.5 everthing worked fine. Now with FS 4.0.1 an error occurred maybe due
to a dimension mismatch.

Dear FS experts
Here I found a warning that seem to be related to the error message I posted
before.
