Hi
This really depends on the units you use for the b values. We typically use s/mm2 for the b values, in which case the diffusion coefficients will be mm2/s. If your b values are defined in different units the dtifit results will reflect these.

Are their unit of diffusivity in accordance to the DTI-TK tool - as specified here http://dti-tk.sourceforge.net/pmwiki/pmwiki.php?n=Documentation.Diffusivity? In this DTI-TK documentation, the authors state that the unit of diffusivity is mm2.s-1 in FSL.
