Connectome dtifit bias inhomogeneity correction or not

Dear community:

I have found this entry in the mrtrix form and I wonder if it is correct to compute dtifit with the preprocessed dwi data after bias inhomogeneity correction or is it better before that step (without the bias correction).

dtifit -k DTI_30_average-2_denoise_preproc_biascorrected.nii.gz -o DTI_30_average-2_denoise_preproc_biascorrected -m DTI_30_average-2_denoise_preproc_biascorrected_mask.nii -r DTI_30_average-2_denoise_preproc_biascorrected.bvecs -b DTI_30_average-2_denoise_preproc_biascorrected.bvals



If I understnd correctly, dwibiascorrection doesn’t affect to the outputs of dtifit. So you can do it before or after.

Best regards,

Note that you can also perform tensor fitting with MRtrix using the dwi2tensor command.
