Hi Julie
what space is the Gordon Parcellation in? Did they use FreeSurfer? If so, then you just need to map it to each of your subjects.
And how is a surface-based parcellation stored in a nifti file?

Hi experts,
I would like to use a different atlas other than the 'default' Freesurfer atlases, namely the Gordon Parcellation (surface based parcellation of 333 ROIs of the cortex) to segment my T1 datasets. So I can go on to use these segmentations for DTI connectome analysis using MRTrix (or MatLab). I have two questions:
- I have this atlas as a nifti file. Do I need to transform this atlas into a different file for it to run in freesurfer?
- Can I run this step in autorecon3 (step 28)? Or should I rerun recon-all all together? If so, could you help me with what commands I need to run (mris_ca_train?)”
Thank you, Julie
