Dear Freesurfer community,

I have the 7-network Yeo atlas in MNI space and as a nifti file as downloaded from the Freesurfer website.

Right now, the atlas has 7 labels for each of the networks. I however want to split this to the left and right hemisphere, ultimately creating 14 labels in a nifti file.

Could anyone share as to if and how this can be done with Freesurfer (I am unsure due to it being in volume and not surface space)?

Thank you.
