It looks like the values vary from 20-120 depending on which region I run the cursor over. However, aren't those the values that correspond to the brain.mgz regions? Is there another way to find the segmentation values?On Mon, Jul 29, 2013 at 10:37 AM, Bruce Fischl <fischl@nmr.mgh.harvard.edu> wrote:

Hi Bruce,
Do you mean the brainmask.mgz values? I'm not sure what the segmentation #'s exactly are.

Hi Mark
what #s are those segmentations? It should be trivial to just add them to the end of the LUT. I wouldn't let them be
out of bounds as there might be code around that might ignore them then.

Hi Doug,
Thanks for the reply. After doing some research, it looks like messing with the LUT might be a
risky decision [and way
out of my abilities!].
If I were to use this segmentation file to create a .gca atlas using the command mri_ca_train, do you
think it would yield
problems or be inaccurate? I guess what I am trying to figure out is if the color lookup values are even
significant when using
the segmentation file to create an atlas?
Thanks for all of the help with this.

I'm not actually quite sure what it means either. When I use the command line:
tkmedit $Subject brain.mgz -segmentation <seg.mgz>,
I can run the cursor over various regions and the name of the region should pop up. For some
reason, the red
regions are simply labeled as "out of bounds."
I'll keep messing with tkmedit and let you know if I find out what the problem is.
Thanks guys!

I do not believe it is a

Could it simply be that the

bad? Is
there an
easy way to open up the

Hi Doug,
Sorry about that vague
explanation. So
I received
a series of infant brain
atlases
from a
UNC medical
research group
(http://www.med.unc.edu/bric/ideagroup/free-softwares/unc-infant-0-1-2-atlases).
I have a series of infant
MRI's that I
would like to
segment (using the infant
atlases,
instead
of the
default adult atlas in
FreeSurfer).
As a preliminary step,
I was
attempting
to check
the alignment of one of
the atlas
files
('avgseg.mgz') with one of the
input brains
('brain.mgz'). [I attached
these two
files, just in
case].
So my command line would be:
tkmedit $Subject brain.mgz
-segmentation
avgseg.mgz
$FREESURFER_HOME/FreeSurferColorLUT.txt
The result was the
previously attached
image. I was
just wondering if there is
any way to
shift the two
images manually so the
alignment is
better? Or maybe
the two files are simply not
compatible
with one another?
Thanks for all the help!
