Hi Doug

I have run recon-all -segstats -s subject on all my subjects, but I can not see total brain volume label. Should I use intra cranial volume?

Hi Knut, you can copy the following file into $FREESURFER_HOME/bin/mri_segstats ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_segstats.linux (assuming you're using linux) The run recon-all -segstats -s subject This will create a new aseg.stats file with total brain volume based on adding up the values in the segmentation. doug

Hello,

We would like to calculate a Total Brain Volume based on data in aseg.stat generated from version 5.1.0. Can I use intra crainal volume as estimated for total brain volume? Or should I just add total grey volume with subcortical grey volume with total white matter volume?

Thanks, Knut Jørgen
