The cutoff is only on screen visually for faster interaction. When you save the transformed volume, it should be complete.

Dear Freesurfer list,

We have been using Freeview's "transform volume" functionality to do AC-PC alignment on some of our T1 scans before processing with recon-all. We had previously been using SPM, but wanted to move to an entirely free method rather than relying on MATLAB. It turns out that, for some scans where a lot of translation is needed to move the subject into AC-PC alignment, the volume will get cut off after performing the transform. This is in Freeview v.1.0 running on Mac OS 10.10.5. When I tried running the same thing in the new version of Freeview (v.2.0), loading the T1 image crashes freeview, which I believe to be a separate issue. Is there any way to do the AC-PC alignment in freeview or freesurfer without having issues with the field of view being cut?

Thanks,

Liberty
