Hi,
The recon-all based striatal parcellations are based on the anatomy of each particular subject, guided by a probabilistic atlas. That is inherently likely to be more accurate that just taking a set of ROIs/parcellations defined in some (non-probabilistic)
atlas and warping them to each subject via an affine transformation, which is what it sounds like you are doing with the "Choi ROIs".
cheers,

Thanks for the response.
I actually got this pipeline partly from Thomas a few months back. However, I wasn't sure if anyone had suggestions perhaps for a recon-all based command for going from the MNI152 1mm template-based fit to individual subjects. The recon-all/Freesurfer
inherent striatal parcellations are so well fitted to even my severe AD patients, so I was hoping I could somehow adapt this to the Choi ROIs.
