Re: [Freesurfer] Troubleshooting incorrect annotations (cortical parcellation)

Hi Sam,

It's kind of suspicious that both hemispheres are so far off. We don't usually see this. Have you checked the talairach xform to see if it is way off? If not, feel free to gzip the subject and drop it for us to take a look at. Do you see this in other subjects?

cheers Bruce

Hi All,

It looks like the annotations are incorrect here, with the Parieto-occipital fissure annotated as the calcarine fissure on the attached surfaces. (Possibly because the occipital cortex seems to be squashed downwards?) The annotations are aparc.a2009s

If that's, correct is there a method to fix the annotations?

Thank you in advance for any help.

Best regards,
