Hello Freesurfer experts:

I am wondering if I can do ACPC alignment in freeview.  Perhaps using Tools> Transform volume  and then rotating using landmarks.

Is this indeed possible? If so, can anyone provide guidance on the 3 landmarks to select (would it be anterior commissure superior & posterior edges & posterior commissure) and how to map these landmarks to coordinate axis vectors?

I would appreciate it.

Thanks in advance,

Tracy Riggins
