Hi Emil
how do the surfaces look before you apply the T2 deformation? And how do
they look visualized over the T2 instead of the T1?
cheers

Hi,
I have been using Freesurfer v5.3 to perform surface reconstruct for 1mm
isotropic T1 (MPRAGE) and T2 (SPACE) weighted images from a Siemens 3T Trio
scanner with a 32-channel head coil. Unfortunately for half of my subjects I
receive an rather odd pial surface artefact, while the 'white' surfaces do
not suffer from the same issue.
The command line I have used was:
recon-all -all -subjid <subjectid> -T2 <subjectdir>/mri/orig/T2.mgz -T2pial
-3T
Are you familiar with this issue and do you have some advice for me?
Thank you very much for your help.
Yours sincerely,
Emil
