Freesurfer experts,
I'm having an issue with projecting labels from an atlas to a subject. I have a static annot file on the atlas that I want to paint onto my subject. The pipeline I have performed is to mris_register my subject to the atlas and then mri_surf2surf on the annot file using the registered spherical surfaces.
The labels, when painted, are incorrectly oriented. How can I debug the output of the registration to check if the registration is working? I assume the registration works in the 2D parameterised space, can I extract parameterised versions of the curvature maps at each iteration of the registration.
The strange thing is that when I view the spherical surfaces in freeview with the overlaid curvature maps they look in alignment prior to registration, but using this unregistered sphere still puts the labels in an incorrect orientation. So it appears as if there is some rotation that is being done internally that isn't shown in freeview.
Please advise,
Chris.
