Hello everyone,
I am experiencing an issue while running the dwifslpreproc
script on my dataset. The process appears to be running fine until it reaches the eddy_cpu
command, after which it fails with a vague error message “EDDY::: Eddy failed with message.”
Software Versions:
- MRTRIX3:
== mrinfo 3.0.4 == 64 bit release version, built Dec 14 2022, using Eigen 3.4.0
- FSL:
FLIRT version 6.0
- Operating System: macOS; Apple M1 Max; 32GB Memory; Ventura 13.5.1
Steps:
- I started by running the
dwifslpreproc
command as follows:
dwifslpreproc dwi_unringed.mif dwi_preprocessed.mif -rpe_header -pe_dir AP -eddy_options " --slm=linear --verbose"
- The script proceeds through several steps like loading headers, executing
topup
, etc., until it fails at theeddy_cpu
command.
Error Message:
The error message I received is as follows:
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 --verbose --out=dwi_post_eddy --verbose (dwifslpreproc:972)
dwifslpreproc: [ERROR] Information from failed command:

Additional Information:
- The
dwi_unringed.mif
was generated from DICOMs usingdcm2niix
and further processed usingdwidenoise
andmrdegibbs
. - The
b0_AP_PA.mif
used indwifslpreproc
is an average of B0s from both the AP and PA directions. - The shell indices and b-values show the following:

I would really appreciate any guidance or suggestions to resolve this issue.
Thank you!
