Summary of what happened:

I’m using fMRIPrep 24.1.0 on a subset (N=40) of the Narratives dataset, there are two subjects failed due to the same reason:

Extreme value 2.21e+04 detected in spline coefficients

when running "fmriprep_24_1_wf.sub_095_wf.fmap_preproc_wf.wf_auto_00004.bs_filter"

Does rerunning help? You should be able to use the same working directory, and just rerun the spline filter. Since the regression is stochastic, there’s a decent chance a second try would succeed.

Yes, I’m rerunning it now with everything. I also removed other irrelevant tasks. I’ll close this one if it succeeds. Thanks!

I encountered the same error while using fMRIPrep 24.1.1 with fmriprep-docker on both Windows 11 (WSL2) and Ubuntu.
Rerunning didn’t resolve the issue in my case. Everything works well when the --use-syn-sdc flag is removed, although I’m not sure to what extent this will affect the final results.

Hi, rerunning (HPC, CentOS) solved my problem. Based on the output, can you identify which tasks/runs having the problem?

Thanks for your information. I couldn’t identify which specific task or run encountered the error based on the fmriprep output. Below is the crash information (similar to what you have).

My command looks simply like this:

fmriprep-docker "${FMRI_BIDS_DIR}" "${FMRI_PREPROC_DIR}" participant --participant-label "$pid" --use-syn-sdc --fs-license-file "${LICENSE_PATH}" --stop-on-first-crash | tee "${log_path}" &

I previously ran it successfully with other versions of fMRIPrep, but with this latest version (2024.1.1), the error occurs for all participants. Therefore, I lean towards ruling out stochastic regression as a potential random cause.

Chiming in - we are also getting this exact error. Always the same handful of participants, and 100% of the time on those particular participants.

Using fmriprep 23.2 fixes the problem.
