Hi there,
I haven't received a reply to my question below.
Just to clarify, I ran autorecon1 and autorecon2 on this subject. When
examining the surfaces in tkmedit, the left temporal pole is not
included in the pial surface. Is there a way to force freesurfer to
recognise this as valid brain tissue, bearing in mind that there is no
visible white matter underneath (and therefore the option of adding
control points is not possible).
Thanks for any suggestion to resolve this problem.

Hi there,
I've run autorecon2 on a subject who has significant unilateral
atrophy in the anterior temporal region. In the last few slices
anteriorly, the pial surface does not include what is clearly
atrophied cortical tissue without underlying white matter. What is
the method to correct for this? Looking at previous queries, all of
them refer to spots where one can manipulate the segmentation by
adding control points in the neighbouring white matter, which is not
present in this instance.
Any suggestion appreciated.
Olivier
