Hello All,
I have a functional beta value overlay as a .mgh file and a label file and I want to compute the average value within that mask for each subject.
Is there a program to do that ?
Thanks
Ri
Hello All,
Looks like this question slipped through. I have a functional beta value overlay as a .mgh file and a V1 label file and I want to compute the average beta value within that mask for each subject.
How do I do this ?
Thanks a lot

Hi Ri
Doug may have something to do this, but if not it would be easy enough in matlab Bruce

Hi,
I believe the mri_segstats program is exactly what you're looking for here.
Best, Michael

mri_anatomical_stats will do that for you. see mri_anatomical_stats --help
it would be something like:
mris_anatomical_stats -l ../label/lh.V1.label \ -t ./lh.beta.mgh \ -f lh.beta.stats \ my_subject_id lh
note that the column name will say 'ThickAvg' and 'ThickStd', which is actually the avg/std for your beta.mgh input file.
