[Freesurfer] Inverse projection query

Dear freesurfer experts: I have been using matlab to analyze a retinotopic dataset. However, the 3D volumes are not in standardized space (and I wish to display multiple maps from different subjects on one surface). Although the initial segmentations were done in freesurfer, my question is: Is

Hi Doug, I am now at the bbregister stage ... I ran this but it is not clear to me where the output is? I don't see an output flag ... Can you tell me where to look for my output? Almost there! Many thanks, Jason. On 04/02/2011 23:49, "Jason Connolly" wrote: Thank you.
