Is it ‘mri_surf2surf’? mri_surf2surf is used when mapping surface data to the surface of an average subject such as fsaverage.

I am wondering > whether I can use my own labeling, like 1000 regions? How can I do this? Do you mean you've labeled 1000 regions on a brain? You would have to do that for a number of subjects (eg, 40), you can then build an atlas. The problem is that such small regions will not be very reliable doug > > Thank you very much! > > Qiongmin Ma > _______________________________________________ > Freesurfer mailing list > Freesurfer@nmr.mgh.harvard.edu > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > >
