apptainer / singularity version requirement

[celstark]

Running your container in apptainer 1.3.4 is just fine. Running it in 1.2.5 (or older versions of singularity) gives the following:

apptainer --version
apptainer version 1.2.5-1.el9

apptainer exec code/dcm2bids_3.2.0.sif dcm2bids --help
Traceback (most recent call last):
  File "/venv/bin/dcm2bids", line 5, in <module>

The prior 3.1.0 though was fine:

apptainer exec code/dcm2bids_3.1.0.sif dcm2bids --help
usage: dcm2bids [-h] -d DICOM_DIR [DICOM_DIR ...] -p PARTICIPANT [-s SESSION] -c CONFIG [-o OUTPUT_DIR] [--auto_extract_entities] [--bids_validate]
                [--force_dcm2bids] [--skip_dcm2niix] [--clobber] [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}] [-v]

Reorganising NIfTI files from dcm2niix into the Brain Imaging Data Structure

options:
  -h, --help            show this help message and exit
...

Note, it does run in the newer apptainer:

apptainer --version
apptainer version 1.3.4-1.el9

apptainer exec code/dcm2bids_3.1.0.sif dcm2bids --help
usage: dcm2bids [-h] -d DICOM_DIR [DICOM_DIR ...] -p PARTICIPANT [-s SESSION] -c CONFIG [-o OUTPUT_DIR] [--auto_extract_entities] [--bids_validate]
                [--force_dcm2bids] [--skip_dcm2niix] [--clobber] [-l {DEBUG,INFO,WARNING,ERROR,CRITICAL}] [-v]

Reorganising NIfTI files from dcm2niix into the Brain Imaging Data Structure

options:
  -h, --help            show this help message and exit
...

Thank you for the issue. I will check if I can make it work otherwise I will need to tell people to update apptainer.
