You'll have to run it on each subject. Easy to do with a script. You can then cat the data into one fine (they are just text files). doug

Thanks Doug, Do I need to run the following for each subject or can is there a way to run it with input for all my subjects in one go to get the brain volume of all my subject in one output file. Thanks,

oh, sorry, I do remember now that we took that out (I think we put it back in for the next release). The work-around is to run
mri_binarize --i brain.mgz --min 0.00001 --count count.dat --o junk.mgh
You can delete junk.mgh. The file count.dat will have info about the number of voxels in the brain. It will have 4 numbers: #voxels in brain, brain volume (mm3), total # voxels in volume, and brain volume as a percent of total volume in the 3d a field of view.

Hello doug, In the asegstats. Txt ( that got as in the table format with information on all subjects grouped together in a single .Xls file) I found information on Total Gray vol but I don't see whole Brain volume. Can you please suggest me where to get the whole brain volume. Thanks, Rashmi.

In the aseg.stats file there is a value for the whole brain volume. doug

I would like know how can I get the sub-cortical volumes normalized it to the whole brain. Thanks, Rashmi.

No, it does not. All volumes are volumes in native anatomical space. doug
