_gather_counfounds : Original files don't match

[g-bond]

Hello,
I'm running the qsiprep-0.15.3 singularity image to reprocess some subjects.
Error is thrown from qsiprep/interfaces/confounds.py.

Here's the qsub call
qsub -cwd -l h_vmem=64.0G,s_vmem=64.0G -l gpu=1 -pe threaded 8 \ -j y -o /cbica/projects/anxiousMisery/qsiprep_work_dirs/postQC_reruns/qsiprep_${sub}_\$JOB_ID.o \ run_qsiprep.sh \ ${data_root} ${sub} /cbica/projects/anxiousMisery/qsiprep_work_dirs/postQC_reruns/qsiprep_${sub}_\$JOB_ID

Here's the script run_qsiprep.sh that's being submitted
data_root=${1}
sub=${2}
workdir=${3}

niidir=/data/raw

cudaInfo=/usr/local/cuda-10.2

singularity run --nv --cleanenv \ -B ${data_root}:/data,${sliceInfo}:/data/slspec/slspec.txt,${cudaInfo}:/usr/local/cuda \ ${img} ${niidir} ${outdir} participant \ --fs-license-file ${fs_license} --notrack \ --nthreads 8 --omp-nthreads 8 \ -w ${workdir} --skip_bids_validation \ --verbose --eddy-config eddy_params_prisma_cuda.json \ --participant-label ${sub} --mem-mb 58000 \ --distortion-group-merge concat --output-resolution 1.5

No issues are encountered until the confounds are concatenated.
Here's the crash report :
crash-20220322-151218-anxiousmisery-concat-4fae89d2-9994-4961-a873-26f6b136a459.txt

This occurs for each subject that we tested under these new settings.
I'd appreciate any help with figuring out what's going wrong.
I haven't been able to understand what the issue is.

Please let me know if the inclusion of any more information could be helpful.
