[Freesurfer] mris_register external atlas

External Email - Use Caution

Hi there,

I am trying to register my Freesurfer subject's cortical surface into a common space to use the parcellations from a pediatric atlas (UNC 4D cortical surface atlas).

With Freesurfer version 8.0.0 in a Linus OS, I am using mris_register as: mris_register -1 individual_subject/lh.sphere 4D_atlas/lh.sphere individual_subject /lh.sphere.FS.reg.

I am getting an error where it says it requires a smoothwm file from the atlas files, though I only have curvature and sphere files from the atlas. Is there a way to register the atlas files to my subjects and then put the parcellations onto my subject's cortical surface?

Thanks, Stefanie
