Hi,
I had 2 questions relating to measuring global mean cortical thickness with
the weighting factor of surface area
bh.thickness = ( (lh.thickness * lh.surfarea) + (rh.thickness *
rh.surfarea) ) / (lh.surfarea + rh.surfarea)
1.) If this weighting is recommended, then shouldn't it be performed f
yes, that is correct. An alternative would be editing the aseg directly.
Editing the wm will help the surfaces but not correct the aseg.
But as Antonin suggests, try running with -bigventricles and see if that
fixes your problems
cheers

Dear list and Eugenio,
I have run for each subject
mri_label2vol --label SUBJ/label/rh.perirhinal_exvivo.thresh.label --regheader
SUBJ/mri/norm.mgz --fill-ribbon --subject SUBJ --hemi rh --o
SUBJ/mri/rh.perirhinal.nii.gz
next, to use FS-FAST on perihrinal.nii.gz, I have run
fcseed-config -seg S
Thanks the problem is resolved now.

Dear FS experts:
I conducted recon-all analysis on my own subjects, and found that there are
several kinds of thickness files, such as the lh.thickness file and
lh.thickness.fsaverage file. By using MATLAB scripts implemented in FS,
different numbers of vertex were found between the two fi
