Hello MRTrix experts,
My question is about preprocessing with preproc step. There is only one phase encoding direction available in my DTI data. Therefore, I am skipping the “Extracting the Reverse Phase-Encoded Images” and would like to continue with preproc step. I tried the following command:
dwifslpreproc Ax_DTI_30_den.mif AX_DTI_30_den_preproc.mif -nocleanup -rpe_none -eddy_options " --slm=linear --data_is_shelled"
However I receive an error “No diffusion gradient table found”. Attached please find the screenshot of terminal.
I’d appreciate any advice on this. How should I move on if our data has only one phase-encoding direction.!
