White matter atlas

I work with data of mean diffusivity of Diffusion MRI .
Which Brain Atlas to use to define the white matter please ?
I find JHU is used for Fractional anisotropy but for mean diffusivity i dont know…
thank you very much

Sorry, I don’t find such an atlas.
I see bundle atlases from HCP, but this is not what you want.

(In dipy there are FA and bundle atlases)
