A pitfall in the reconstruction of fibre ODFs using spherical deconvolution of diffusion MRI data

► We compare two spherical deconvolution based fODF retrieval techniques. ► We examine fODF error under inappropriate response function calibration. ► CSHD produces errors as response and target diffusion profiles diverge. ► dRL is poor against low FA targets but adequate across white matter. ► Manuscript updated to cover orientational dependence of CSHD errors.
