How to compute cortical schaefer 300 parcellations

Hi Raymundo,

Thank you for your quick reply.

I am not very familiar with using freesurfer. However, freesurfer was already run on the data I’m referring to, and has produced the surface files for each subject (eg. lh.sphere.reg) which I tried running with ‘mris_ca_label‘ as follows:

mris_ca_label -sdir . -orig sphere.reg Subject1 lh Subject1/surf/lh.sphere.reg lh.Schaefer2018_300Parcels_7Networks.gcs lh_300_v2.annot

Does this make sense? Or could you highlight the difference between using this reg file directly vs doing the 1st freesurfer step you mentioned previously.

And then, I tried steps on this page: How to import other brain atlases to use as scouts - #3 by Jeff_Eriksen . But I am unable to import the file successfully.
