Dear all,
I would like to work with the pial surfaces of my database and more
particularly with a point-to-point correspondance between each subject. But
I didn't find how to do that, only for longitudinal analysis of a single
subject which I am not interested.
Thanks in advance for you help,
Hi Alexandre
can you tell us what you want to do with the point-to-point
correspondence? We don't usually map surfaces into a common space since
we want to have uniform resolution/sampling in the individual coords.
cheers

Hello Bruce,
I would like to build an atlas of subcortical structures and pial surface
on my population of study. But given the anatomical complexity of the pial
surface (and the number of points), I would like to use point-to-point
correspondence so as to have a L^2 metric (I use another metric
I'm not sure what you mean by working with the pial surfaces with
respect to point-to-point correspondence. Can you give more info?

What I wanted to say is that there is the exact number of points of the
pial surface for each subject and if I look to the i-th vertex of the pial
surface of a given subject, it should be located on the same area for
another subject.

This is not something we support.

Oh, okay. I thought this kind of data could be obtained since it exists for
longitudinal analysis.
Thanks for your answer anyway!

you can just compute the jacobian of the ?h.sphere.reg for deformation. I'm
not sure I understand how you would use an L2 metric. There are tools in
AFNI/SUMA for converting a freesurfer surface to a standard mesh that you
could use

no, but I think SUMA does. Check it out. I'll cc Ziad so he can chime in.

Okay, thanks for the answer, I'll have a look on this software.
