External Email - Use Caution
Thanks Tim.
I'd like a set of points on the surface to compare across
subjects, where there are the same number of points for each
subject and they're roughly in the same "physiological position"
on each subject. So again, if on my atlas I have a point which
is at the top of the ctx-rh-fusiform sulcus, I'd like that point
to be registered to the top of the ctx-rh-fusiform sulcus in my
subjects.
External Email - Use Caution The registration registers the meshes, but it does not alter the number of vertices in them. There is no 1-to-1 correspondence between the vertices of the 2 meshes. May I ask why you need this? What do you want to achieve?

I do not understand what kind of registration would reduce the number of points. What is the relationship between the first point in --src_xyz file and the first point in the output registered file? If I halved the number of points in the input, would I expect the output to be half the size? Or less? I'm sure there's a simple explanation that I don't have my head around just yet - thank you for your patience. Ian On 07/05/2020 22:45, Douglas N.
