Hi,
For the HCP data I presume the gradients non-linearity saved in grad_devs.nii.gz would need to be taken into account to fit the DT but i cannot see any option for this in dtifit.
Could you please recommend which b-value to choose for the calculations of the DT and how to apply the gradient non-linearity correction? I know this is a shame to compute the DT on the HCP data but I would still need the FA, MD, etc. maps.
Many thanks,
Michael
