Hi,

On a HPC I run:

singularity run --cleanenv \
    -B $DATA:/data \
    -B $FS_LICENSE:/fs-license \
    $LAB_PATH/Singularity/tigrlab_fmriprep_ciftify_latest-2019-08-16-6ea864911724.simg \
    /data/BIDS /data participant  \
    --participant_label=${SBJ} \
    --session_label=01  \
    --fs-license="/fs-license/license.txt"  \
    --read-from-derivatives /data --debug --anat_only --rerun-if-incomplete

About once of every 10 subjects I get

Any ideas?

Other than that, thanks so much for creating this tool! Uri,
