Hi Bruce,

Thanks for your reply. Those functional ROIs are volume-based (that is, generated by spm/fsl/BrainVoyager).

So it seems that I need to generate a label for them in order to use mris_anatomical_stats -l.

Do you know what I can generate label files based on volumetric functional ROIs? I'm also a little bit puzzled because a given functional ROI may not capture the whole gray matter within a certain region, how can we determine its volume/area/thickness?

Many thanks!
Daniel

yes, if they are surface-based then it is really trivial (just give them to
mris_anatomical_stats with the -l <label name> flag)

Dear FreeSurfer Experts,
Theoretically, if you have a set of functional ROIs, is it possible to
derive the cortical thickness, white surface area, and gray matter volume of
those functional ROIs in FreeSurfer?
Many thanks!!
Daniel
