Since I don’t know what you are talking about, how about posting an image from
the sequence you have in mind to use…

Thank you for your reply.
However, my questions referred to whether a 3D Flair could also work for pial
surface correction, or only 3D T2 flair is suitable and if it is ok for all
participants not to have the same slice thickness on Flair, as I previously
wrote most of my participants have slice thickness 1mm but some have 1.48 mm.
Thanks again,
Georgia

Hello Freesurfer Developers,
I am conducting a group analysis between a patients and a control group. I have
accomplished recon-all individual analysis and I want to correct pial surface
using 3D Flair.
I would like to ask two specific things:
1. Is 3D Flair appropriate or only T2 Flair is recommended for such correction.
From what I have read on previous posts, it is usually recommended to use T2
Flair.
2. For my data, for most of my 3D data slice thickness is 1 mm, but for some of
them is 1.48 mm. Is that difference going to affect analysis results?
Thank you in advance,
Georgia
