Hi Inês
it's tough to tell from a few images. I would guess it is a topological
defect caused by a spotty segmentation. If you tar and gzip the entire
subject dir and ftp it to us with the location of the problematic areas
we will take a look
cheers

External Email - Use Caution
Dear FreeSurfer developers,
I am reaching out again because the issue mentioned in the previous email.
I have successfully edited many other subjects, but this one still eludes me.
I am pretty sure the places where I placed the control points represent WM and
I also clearly see
excluded cortex.
Since the pial surfaces do not update after WM editing, could you help me
understand what the
problem could be?
I am resending you the images, so you better understand what I mean.
Have a great day!
Best regards,
Inês Pereira

Dear FreeSurfer developers,
I am trying to obtain adequate pial surface boundaries.
Unfortunately, on a few subjects, some grey matter is being excluded from the
pial surface, at
the temporal pole.
I have attempted to solve this problem by adding control points and adding
voxels on the wm.gz
volume, so as to have FreeSurfer first update the wm boundary and then
hopefully the pial
surface.
As you can see on the attached images, the control points were only partially
taken into
account and the pial surface was not updated.
It would be great to get your support in understanding why this is happening.
I am using the following Freesurfer version on
Centos: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
Thanks!
Best regards,
Inês Pereira
