Dear experts,
I try to perform the fixel-based analysis of fibre density and cross-section.But there is a WARNING when I using the script of dwipreproc.
The command of I used is following:
foreach * :mrconvert IN/dwi.nii IN/dwi.mif -fslgrad IN/dwi.bvec IN/dwi.bval -datatype float32
foreach * : dwidenoise IN/dwi.mif IN/dwi_denoised.mif
foreach * : dwipreproc AP IN/dwi_denoised.mif IN/dwi_denoised_preproc.mif -rpe_none
Then occured the WARNING:eddy has not provided rotated bvecs file;using original gradient table.
However, I obtained the output dwi_denoised_preproc.mif finally.
But I did not know the reason that the WARNING occured. And the dwi_denoised_preproc.mif that I obtained is right?
Thanks,
Mirabelle
