Hello MRTRIX community,

I am trying to use MRTRIX to calculate a kind of complicated case of FODs.

Is there any way to use the dwi2responce function based completely on the measured data (for example dwi.mif) and selected voxels for the kernel calulation, which does not include tensor calculation by MRTRIX?

I would assume that -in theory- the kernel can be calculated without a-priori knowledge of directionality. In case this is not possible, is the -dirs parameter (of the dwi2reponse manual) working with providing the tensor for each voxel in FSL form (eg. a volume of size [x z y 6], where 6 the tensor components)?

Thank you!
