Hi FS-ers,

I'm a bit stuck trying to compute cortical and subcortical statistics using the Buckner 2011 Cerebellum mask.  I tried using mri_segstats to generate the .stats file for the provided image:

mri_segstats --seg Buckner2011_7Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz --sum test.summary --ctab-gca Buckner2011_7Networks_ColorLUT.txt --nonempty

Clearly I am doing something wrong.  Can someone throw a pointer my way about how I can go about computing statistics on my subjects (or any arbitrary volume) using this mask? 

In the end I would like to be able to generate a .stats file for every subject in my SUBJECTS_DIR using any custom mask.. how can I make this possible?

Your help would be very greatly appreciated!
