Hi Matt – It looks like some sort of registration issue. When you display the FA map (dmri/dtifit_FA) and structural segmentation in diffusion space (label/diff/aparc+aseg), do they look fine? Is there any part of the brain that is cut off from any of the images? Also, can you attach your config file? Thanks!
