Christine,
This would do it:
mri_segstats --annot fsaverage lh aparc --i sig.mgh --sum out.txt
where this will find the means for the 'aparc' ROI's, for the input file sig.mgh (assuming it was produced by some group analysis, like mri_glmfit or qdec), and produces output text file out.txt.

Hi,
Just wondering whether it is possible to extract values from an overlay created on fsaverage for aparc parcellated regions e.g. the mean of a statistical test parameter for specific aparc ROIs?
I know it is possible to extract values for individual subjects on the basis of fsaverage ROIs, but all I would need is the mean for individual ROIs on fsaverage.
Thanks for your help!
