Dear Freesurfer team,

I've scanned a group of subjects and gained structural and myelination data. Then, I've used mris_preproc to map the data onto the surface of fsaverage (and concatenating the data). I would like to investigate the correlation between cortical thickness and myelination by mapping this correlation onto the fsaverage (an one sample group mean analysis) - is this possible? Do you have an existing guide approaching this problem?

Thank you!

Best, Silas
