Greetings,
I am trying to determine how bad a talairach.xfm registration has to be to warrant a manual edit. I have found that even minor edits can have noticable (9%) effects on major subcortical volumes (such as thalamus or hippocampus). Very few registrations seem to have completely failed, but most seem like they could be made better by a tweak here or there. At what point would I just be adding randomness by manually editing?
About what percent of a given dataset would you expect to manually edit?
Much appreciated, -Eric Cunningham
