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 for subcortical structures).

I don't know if I am clear enough but since I estimate the template and the variability between the template and the subjects, I would like to detect information such as atrophy thanks to the deformation parameters.

Is there any solution?

Alexandre

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
Bruce
