“--slm=linear”: is an unrecognised token!

Dear all,

I am following BATMAN structure to run test codes (MRtrix3.0.8 on a macbook M4):

Now I want to run motion and distortion correction with dwifslpreproc command:
dwifslpreproc dwi_den_unr.mif dwi_den_unr_preproc.mif -pe_dir AP -rpe_pair -se_epi b0_pair.mif -eddy_options “–slm=linear”

, but I get this error:
“–slm=linear”: is an unrecognised token!

btw, running this line successfully produced the file “dwifslpreproc-tmp-47DCZC“, which meaned the rest codes were fine, it was the [“–slm=linear”] went wrong.

i am totally new to this, it would be greatly appreciated if someone can help.

thank you so much.

also with these error:
dwifslpreproc: [ERROR] eddy_cpu --imain=eddy_in.nii --mask=eddy_mask.nii --acqp=eddy_config.txt --index=eddy_indices.txt --bvecs=bvecs --bvals=bvals --topup=field “–slm=linear” --out=dwi_post_eddy --verbose (dwifslpreproc:1004)
