Re: [HCP-Users] Resting fMRI Cortex Vertices Indices

[Glasser, Matthew]

Yes they are and they have correspondence across subjects.  That is the point of being on standard meshes and a standard atlas set of subcortical voxels in the 2mm CIFTI grayordinates space.  The reason that not all surface vertices are included is because the medial wall is not cortical grey matter. Peace, Matt.

And for CortexRight, it tells which 29716 vertices out of 32492 are included. My question is are all the vertices indices in CortexLeft (29696) and CortexRight (29716) the SAME for all the subjects? Thank you very much for your time!
