HCP dwi data pre

1

Hi all,
I’m working on HCP dwi data, according to GitHub - civier/HCP-dMRI-connectome: MRtrix scripts to generate dense weighted structural connectomes from the Human Connectome Project "minimally pre-processed" diffusion MRI data tutorial.I would like to ask the difference between these two commands: “mrconvert data.nii DWI. mif-fslgrad bvecs bvals -datatype float32-stride 0,0,0,1” and"mrconvert data.nii DWI.mif -fslgrad bvecs bvals".
Best wishes!

I notice that "data strides“ parts are different. Is that important?

By the way, I’m doing this with minimal pre-processed data.
