Hello All,
Does freesurfer generate a file with total brain volume after the recon-all procedure? Where can this be accessed?
Thanks,
AR.
Hi Anil,
There are two values in the aseg.stats file - BrainMaskVOl and BrainSegVol. BrainMaskVol is the volume of all the voxels that are included in the brainmask.mgz volume. BrainSegVol is the volume of all the voxels that are labeled in the aseg.mgz segmentation.
There's also an estimated total intracranial volume (eTIV) in aseg.stats -- not the same thing as brain volume but close enough that you might be interested.
