Error with plot peaks crashes qsirecon

[aazor]

QSI recon/DSIstudio autotrack won't run successfully. I encountered a 'FileNotFoundError' during QSIRecon processing, specifically when trying to generate the peaks_mosaic.png file in the plot_peaks node. The workflow fails during this step with the following error:

FileNotFoundError: No such file or directory '/path/to/output/peaks_mosaic.png' for output 'peak_report' of a CLIReconPeaksReport interface.

Additional details

• QSIRecon version: 0.22.1
• Docker version:
• Singularity version: apptainer 1.1.7

What were you trying to do?

Run QSI recon/DSIstudio autotrack after successfully running qsiprep.

What did you expect to happen?

Get autotrack results (successfully tested on another population. This population is more challenging from an anatomical perspective)

What actually happened?

This error occurred after the successful execution of the gqi_recon node.

Reproducing the bug

Tried running qsiprep and psi recon back to back. Only got results for qsiprep. Ran qsirecon only (code below).

# Check if QSIPrep outputs already exist
if [ ! -e ${output_dir}/qsiprep_${qsiprep_version}/${subject}/ses-T1/anat/${subject}_ses-T1_desc-preproc_T1w.nii.gz ]; then
    echo "Running QSIPrep for ${subject}"
	
	# Define the QSIRecon command (adjust if needed)
    qsirecon_cmd="apptainer run -B ${scratch},${templateflow_dir} $qsiprep_IMG --participant_label ${subject:4} -w $scratch --output_resolution 1.25 --longitudinal --unringing-method mrdegibbs --recon-spec dsi_studio_autotrack --fs-license-file ${scratch}/license.txt --skip-bids-validation --notrack --mem_mb 60000 --nthreads 12 --omp-nthreads 8 --stop-on-first-crash --recon-only --recon-input $scratch/data/derivatives/qsiprep $scratch/data/ $scratch/data/derivatives participant"

    # Run the QSIRecon command
    echo "Running QSIRecon for: ${subject}"
    ${qsirecon_cmd}
else
    echo "QSIPrep output not found for ${subject}, skipping QSIRecon."
fi
