Thanks,
I did as you suggested, but got a different error telling me that
mris_anatomical_stats cannot be used with fsaverage as it is an average
subject.
You can try the following "hack": convert the annotation to a series of
labels, and then use 'mris_curvature_stats' on these label files. It
will dump a bunch of curvature-related measures, but you can ignore
these and just extract the surface area measures that it also generates.
$>mri_annotation2label --subject <SUBJ> --hemi lh --annotation
lh.test.aparc.annot --labelbase base
This will create a series of label files, base-XXX.label in the
<SUBJ>/label directory. You can use 'mris_curvature_stats' on each of
these label files. Pass it any curvature file, and just grep for "ROI":
$>mris_curvature_stats -l base-000.label <SUBJ> <hemi> curv | grep ROI
