Hi freesurfer team,
I extracted the cortical thickness values using aparcstats2table command
and I got the cortical thickness values for 34 regions and mean cortical
thickness for each hemisphere. But when I averaged the cortical thickness
from those 34 regions regions it was different than the me
Hi Nabin
unless the areas are the same size, the mean of the areal means won't
equal the overall mean.
cheers

Dear FS experts,
I will re post this thread again looking for your help and support:
I ran cortical thickness analysis between two groups using Qdec and I want to correct the results for multiple comparison.
In Qdec there are two choices to correct the data for multiple comparison (FDR and m
Dear Bruce,
Thank you for the response. So, I more thing if I want to get the mean
cortical thickness for whole brain I could simply take the mean between
both hemisphere ? If I understood right from the FAQ.
Q. I am trying to measure the global mean cortical thickness (i.e combined
across hemisp
the mean across both lh.cortex.label and rh.cortex.label should be pretty
close. If you want it to be exact you should weight by area then
normalize
