I believe it does, although the integral values are a bit suspicious. Maybe Doug or Nick knows? On Mon, 8 Jul 2013, Satrajit Ghosh wrote:

does this generation take partial volume into account? this is the default output from running recon-all (from 5.1.0).
cheers,

this seems vanishingly unlikely to me, particularly with partial volume correction. Have you visualize some of the subjects that have the same structure volume?
