You could:
A) Segment a structural scan on which you drew the ROI into grey matter,
white matter, and CSF using FAST.
B) Use avwstats++ <hard segmentation output> -l 2 -u 2 -k <your ROI> -V to
find the volume of grey matter (value is 2 from the segmentation) masked by
your ROI.
Peace,
Matt.

Subject: [FSL] volume of gray matter within a ROI
Dear Friend:
I have defined a ROI and want to measure the volume of gray matter within
this ROI. What is the procedure?
Thanks a lot.
