Dear all, I have an a priori ROI mask previously created in AFNI for functional data. My hypothesis requires me to derive cortical thickness values for the same ROIs. How would I obtain the values using these ROIs from freesurfer? The mask was generated in Talairach space and are surface level ROIs. I tried using mris_anatomical_stats but it didn't seem to work (possibly because the masks weren't created using freesurfer/weren't saved in .label files). How would I proceed? I realize this is probably pretty simple but I'm new to freesurfer and really appreciate any guidance.
Hi Sonya
you are probably better asking the AFNI folks how to output a freesurfer label. I'll cc Ziad on this so he can chime in.
