Hi, I've been looking through the mailing list archives for anything on calculating BPF (Brain Parenchymal Fraction) and have only found some fuzzy descriptions of how to calculate this using FreeSurfer. I know I can get ICV from the aseg.stats, but how can I obtain the volumes of total white and gray matter (i.e. total brain parenchyma volume)?
One possible method I saw suggested mris_anatomical_stats-- but that looks like it only calculates gray matter volumes. Any ideas? Thanks in advance for your help!
