Best way to import Schaefer parcellations

I have individual anatomies of all participants and the FreeSurfer segmentation (conducted before I gained access to my data), and I need to get access to the Schaefer parcellations.
I'm using surface based EEG source reconstruction, so using 'Add MNI parcellation' does not work for me as it imports a volume atlas. Other than re-segmenting using CAT which is very time consuming as I have 60 subjects, is there any other way I can extract the Schaefer surface based atlas?

Thank you very much!

Please check this tutorial:

The Schaefer atlas is included. thanks,

As it is indicated in the link shared by @Anand_Joshi, you would need to compute the cortical computations when processing the MRIs with FreeSurfer.

An non-optimal approach would be to project the desired Schaefer atlas from the Default anatomy to the Subject anatomy. This projection is based on the MNI-normalization.

  1. Double-click the cortex_15002V in the Default anatomy

  2. Select the desired Schaefer atlas in the Scout tab

  3. Create a copy of this Atlas (because the pre-defined atlas cannot be modified)
    Menu: Atlas > New atlas > Copy current atlas

  4. In this new copy, select all the Scouts (Ctrl-All), then use the Menu: **Project to... > SUBJECT > CORTEX_15k **

Note: In this case, the projection happens between cortices with 15k vertices, try to do the projection between cortices of similar size


Left: Schaefer 100 parcellations, 7 networks on the Default anatomy
Right: Same atlas project to a Subject anatomy
Please note that this is only an approximation using the MNI normalization. The proper way to obtain the parcellation is during the MRI segmentation process.
