Dear expert,
Our group have some data scaned from 7T scaner. I would like to calculate the
cortical thickness of the data, however, when I processed them as I do for data
from 3T scaner, I can not run recon-all command successfull to the end. Could
you give me some suggestions on how to
Hi all,
I am doing a study with FreeSurfer (80 subjetcs till now), and I have cases
reconstructed with the versions 4.2 and 4.3. I want to continue the study, and
install the 4.5 version. I saw that in this release the Destrieux Atlas was
updated. Could i compare the cases from the versions

Hi Sima,
it's hard to say just from the tiffs. A couple of things you can look at:
run mris_euler_number on the lh.orig.nofix and the rh.orig.nofix. Better
sequences should result in bigger (less negative) euler numbers.
Plot the intensity distributions of the gray matter, CSF and the white
Dear experts,
I have 2 questions:
1) I created labels for some ROIs on fsavgerage (qdec analysis). I got
statistics from these rois for each individual subject (by map-to-subjects,
etc.), but what I am now interested in is to know the size of the ROI on the
group level (so on the fsaverage
Try something like this
mri_segstats --slabel fsaverage lh path/to/lh.yourlabel.label --sum
lh.yourlabel.sum
The 4th column of the summary file will have the Area in mm^2

Hi All!
Could anyone help me in 3 questions regarding Qdec and freesurfer?
1, I'd like to know what Curv does stand for? Because We have a highly
significant difference in Curv among our groups unilaterally.
2. Is it possible to list the total brain volume for all my subjects? If so,
how to
