Hi Freesurfer experts,
Does reconall register each T1 to fsaverage space?
And if yes, are the Desikan-Killany and Destrieux atlas labels still applicable?
I am asking because I noticed that when I overlayed the Desikan-Killany atlas onto our reconall outputs they didn’t seem to align properly,
Thanks,
Emma

Hi Emma
the surfaces are aligned to fsaverage space, which can be extended into the volume using Lilla's CVS tool. Can you give us more details about what you mean about the Desikan-Killany atlas not aligning properly? You shouldn't look at it directly - you should look at the ?h.aparc.annot. That is the estimate of the DK atlas locations in the individual subject surface.
cheers Bruce

Dear Emma,
to see the labels for native space data or surfaces (e.g., <subject>/surf/lh.thickness), you should use the $SUBJECTS_DIR/<subject>/label/?h.aparc.annot files.
For data that has been mapped to fsaverage (e.g., lh.thickness.fwhm10.fsaverage.mgh), you should use the fsaverage versions in $FREESURFER_HOME/subjects/fsaverage/label/?h.aparc.annot.
Unless something went wrong with the registration, they both should look fine.
Best,
Tim
