Hi Michael If you need anatomical segmentations with high accuracy, you might want to consider using the Hammers atlases (http://www.brain-development.org, follow Atlases-Adult). We've had great success in propagating and fusing these in target space, bypassing the need for spatial normalization (see http://www.soundray.org/maper). We use IRTK and Nifty Reg for the registration, and FSL just for tissue classification, but it should be feasible with FNIRT, too.
