This is also what mri_surf2surf and mri_label2label do too. You can use label2label to check your results as well by creating a label with your given xyz point and mapping it to another subject.

yes, that's basically what "send to subject" does in tksurfer. You can use it to check your results.
cheers, Bruce

Hi Bruce,
I see, the ?h.sphere.reg files are a surf file and the coordinates specify a sphere (surprise, surprise). I assume these are coordinates given after the spherical morph into the target brain space (eg, average7). My interest is in locating a cortical vertex for subject A and then finding all the spherically coregistered vertices for other subjects. To find coregistered vertices across subjects, I assume a 3D distance metric for the ?h.surf.reg data would work. That is,
a) select vertex V from subject A b) extract the spherical coordinates from ?h.sphere.reg for V c) find the nearest vertex in the ?h.sphere.reg file for subject B, using a linear 3D Euclidian distance metric
Will that give the result of the cortical spherical coregistration across subjects (after spherical morphing to the template brain)?
Thanks, Darren
