Hi everyone! I got an error when using dwifslpreproc! I used the code "dwifslpreproc denoised.mif proc.mif -fslgrad dwi.bvec dwi.bval -rpe_none -pe_dir AP -eddy_options “–data_is_shelled --slm=linear” ". But I got --data_is_shelled: Option doesn’t exist. I’ve tried adding Spaces or = before --, but it doesn’t work

Hi @Qianhui_Xu,
Can you provide the full output of the command when running with the -debug option? You can copy/paste the output into your post, just make sure to enclose it in triple backticks (```) to preserve the formatting as it was – it really helps to have the exact output, not the user’s interpretation of it, since that allows us to figure which exact line of code the error originates from, etc.
All the best,
Donald.
Dear Donald, thank you very much for your prompt reply！ Below is the complete information of the output error.txt. I hople it helps.

--data_is_shelled: Option doesn't exist!
Dear Qianhui,
The usage of -eddy_options is to add one space before --data_is_shelled. However, based on the eddy_openmp output, you are using an outdated FSL version; there are no “–data_is_shelled” or “–mporder” or other recent tools implemented in EDDY in the options. Ask your admin to update the FSL and I think then you’ll be good to go.
Best,
Amir

Hi Dear @Qianhui_Xu ,
i am having the same error. Did you successfully resolvedthis issue?
Thanks a lot for your useful advice! It works well on FSL 6.0.3.
Dear shahzadali, as Hussein mentioned, you need to check the version of FSL you are using and ensure it is 6.0 or above.
