I don't think so, but perhaps Nick can comment. Are you positive you
didn't run -autorecon2? Actually, maybe the placement of the ribbon will
change the partial volume estimates for some subcortical structures? I
can't remember the current sequence of events. Nick or Doug: do you know?

Hi Bruce,I run FS 5.1.
So for 5.1 version is it normal that post editing aseg values ar different
from pre editing even using autorecon2-cp?
Thanks again

I think it is, but I would visually inspect them. What FS
version are you running? Earlier versions reran the aseg for
autorecon2-cp, but 5.3 does not

Thanks Bruce,but I'm sure I ran autorecon2-cp autorecon3:
recon-all -autorecon2-cp -autorecon3 -subjid.
However, is it ok to use aseg values post editing even if
they look different from the pre editing
ones?
Thanks a lot.

Hi Claudia
if you run autorecon2 you will rerun the aseg, which
will use the control points to change
the subcortical intensity normalization. If you
don't want that to happen, you need to run
-autorecon2-cp

Dear Freesurfers,we recently processed a
sample of adult patients and then we
reran autorecon-2 and
autorecon-3 after editing contol points, white
matter and pial surface.
We exported the asegstat table both pre and
post editing, and we got different
volumes for most of the
subjects.
How is that possible, given that the kind of
editing we performed is not
supposed to affect subcortical
segmentation?
Thanks a lot.
