Hi Antonin, 

I had answered that in my email from Nov. 18.. 

Thickness is not constrained to 3.5mm, but see my email for the full answer.

Best, Martin

[Freesurfer] mris_make_surfaces - longitudinal stream - questions

[Antonin Skoch]

Dear experts,

I am trying to understand what is the specificity of the pial and white surface 
generation in longitudinal stream, i.e. how the information from processing of 
base template is used for surface estimation in -long step of recon-all.

Specifically:
Why the maximal thickness is constrained to 3.5 mm (default in cross-sectional 
stream is 5 mm)?

What is precisely the significance of -long parameter of mris_make_surfaces?
In the source code is written, that this directive resets starting position of 
pial surface to be slightly inside the orig_pial.
What is the objective of this step?

Regards,

Antonin Skoch
