The most concise way to save these is using the spherical harmonic
coefficients that are used to derive the ODF. Deriving the ODF from these
coefficients anew is not nearly as time-consuming as computing these
coefficients in the first place. I have been saving these as NiFTI files,
because this allows me to save them alongside the spatial transformation of
the data (the affine), so that doesn't get lost along the way.

Cheers,

Ariel
