How to import other brain atlases to use as scouts

A research assistant in our lab did it about 2 years ago using Freesurfer tools. I think you know the process: align each individual to the generic Yeo atlas on the sphere, then map to the individual cortex inflated to a sphere, then map back to the folder 3D cortex, then to the voxels if you need that as well. I hope to learn how to do this soon as I will have new subjects I will need to perform it on.

Another question comes to mind. Now that I have manually imported the Yeo atlas as well as Destrieux, Desikan-Killiany, Brodmann, and two others we have here, I want to subparcellate to use as a scout. But I have to do that for each individual, and they will not mecessarily match. What I really probably need to do is subparcellate in the general Yeo or other atlas space. So I presume I have to do that first in Freesurfer, using the FS parcellation tools, then create an individual subparcellation “labeling” before importing each individual into BST.
