Hi Bruce and Matt, I should specify that I am working with non-human primate data, so unfortunately, looking at the parcellations would not work. I am aligning individuals to a a custom template that I made. I was wondering whether there is maybe an output file that has something numerical on how much one surface had to be transformed to be aligned to the other. I could alternatively compute the square difference between the two surfaces, or something like that. Thanks! Caspar

Hi Caspar
the easiest way it so look at the parcellations and see if they are accurate. Note that we do subject-to-atlas alignment, not subject-to-subject (you get the latter by composing two atlas transforms)

to
a bunch of other alignments to see whether it was worse than the others. Thanks, Caspar
