Dear Mrtrix experts

I am trying to run dwi2response using the following code:

but i encounter to this error massage:
Error: unrecognized arguments: –voxels voxels.mif
Usage: dwi2response dhollander input out_sfwm out_gm out_csf [ options ]
(Run dwi2response -help for more information)

how i can fix this error?

Hey Milad,

You’ve used an en dash character rather than a hyphen for the -voxels option (it’s subtle, but if you look closely, you can tell it’s a little bit longer than the other hyphens in your command line). Copy-paste this, and it should work:

dwi2response dhollander sub-14426_session1_denoise_preproc_unbiased_dwi.mif wm.txt gm.txt csf.txt -fslgrad sub-14426_session1_dwi1.bvec sub-14426_session1_dwi1.bval -nocleanup -voxels voxels.mif
