Hi all,
How was the fsaverage aseg.mgz (in the 4.5 distribution, if it differs)
created? I can't seem to find this information anywhere on the Freesurfer
website.
Thanks!
Mike

Hi,
This is Kumar. I am a grad student at the Dept of Biomedical Engineering,
University of Florida.
I would like to bring to your notice a problem that I am facing when I am
running FreeSurfer on my mac at the lab.
I am testing the freesurfer installation as documented on the Free Surfer
Wiki.
Hello all,
I am using surface tracking in FSL to align my freesurfer surfaces to my
diffusion data. I am wondering if it were possible to use the freesurfer2fa.mat
registration file as the registration input for mri_label2vol. The
freesurfer2fa.mat was generated using FLIRT in FSL by registeri
Hi Brian
I don't know which parcellation you are using, but in the sulco-gyral
parcellation (aparc.a2009s.annot), the fusiform appears as "G_oc-
temp_lat-fusifor"

Hello I am trying to retrieve the fusiform volumes of a sample. I looked in the
subject output files but didn't see any mention of the fusiform and when I
searched the website so far all I could find involved fsl and functional data
which mine is not. If it is possible to do could you please poi
Sorry, my initial reply went to just to Laura, and not the list.

Hi MIchael,
thanks so much for your answer. Fi
Is there total overlap between group and number of slices? Sounds not
very good. I don't have a feel for what the MR on this and whether
changing the number of slices would create systematic differences in
SNR or contrast. Maybe Andre would like to weih in.

Yes I do see values for cc in the stats file thank you!

You'll also find it listed in the aseg.stats file in the stats dir as
cc-anterior, cc-posterior, etc. (labeled as the same when viewing the aseg.mgz
in tkmedit). do you see values for the cc in the stats file?

tkmedit. What version of FS are you using? Older versions did not have
CC defined, but it would have to be pretty old.

Thank you for that Doug, I just had a look in the aseg.mgz file, but unless I'm
blind, I can't seem to see it...could you tell me what it's labelled as please?

The corpus collosum is labeld in the auotmatic volume segmenation
(aseg.mgz). The prefrontal cortex is subdivided into a number of
regions in the auotmatic surface parcellation (lh.aparc.annot or
rh.aparc.annot)

Hi freesurfers!
We want to estimate the differences of cortical thickness between two groups.
The images of the control group are taken from a different acquisition session.
the only differences would be the number of slices (200 vs 128).
It is still possible to compare the two groups?

How did you create the .label files? mri_label2vol (your last step)
does not produce them. Maybe with mri_cor2label run on the output of
mri_label2vol?

Hello FS experts,
A quick question, I'm looking for specific brain regions, but I can't seem to
find them in the files once processing has been completed, I'm just wondering
if FS does processing for areas including prefrontal cortex and corpus collosum?
Thanks,
Fatima
