great, so if I can read the header from the aseg file and the header from the rawavg header file I would be able to transfer any point from the aseg space to the rawavg space is that correct ?

it registers them based on the header information, but since the aseg is derived from the rawavg that should be exactly correct

Hi Johnson
I believe it resamples the aseg to have the same geometry as the original scan.
