have you double checked the orientation of the data in freeview? Eg, is the axial view in freeview truly showing you the axial view of the brain?

Hello all, I have an issue with a study, and am wondering whether it can be fixed. Freesurfer version:

freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c

I am getting a bad talairach output message and when I try to address it with tkregister2 it seems that the orientations are off with coronal sections being treated as sagittal.

I assume there is an issue with acquisition. The raw data through freeview looks Ok.

all the best,
