Hi Yerong
the indices and names are all in the FreeSurferColorLUT.txt file. The
indices in [1000,2000) are for lh and in [2000,3000) are rh. For example,
2008 is ctx-rh-inferiorparietal.

Dear Bruce:
Thank you.
So my question would be if aparc+aseg.mgz is from ?h.aparc.annot and
aparc.a2009s+aseg.mgz is from
?h.aparc.a2009s.annot.
Then how I can find the mapping between labels in aparc+aseg.mgz to
labels in ?h.aparc.annot?

Recon all takes the vertices and assigns them to a parcel using the gcs
atlases ... these labelings are the annot files and they are used to
generate the autoparcellated pial surfaces
Because there are 3 atlases in the recon all pipeline... three
Hi Yerong
the parcellations are done on the surface to generate the annot files.
These are then sampled into the cortical ribbon to extend the aseg so that
every voxel in the cortex is given a label from the corresponding annot
file (aparc+aseg.mgz from aparc.annot and aparc.a2009s+aseg.mgz

Dear Freesurfer experts:
I am on ROI analysis tutorial:
https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROIV6.0
And I am trying to understand the relationship between:
/label/?h.aparc.annot and /mri/aparc+aseg.mgz
