Only T2w image

[seonjoo]

What happened?

I have only T2w and BOLD images. But it keeps givine me errors: "FileNotFoundError: No T1w images found for subject". The current implementation of NiBabies do not handle the cases without T1 image? Or is it a bug?

What command did you use?

docker run --rm -e -it -v ${datadir}:/data:ro -v ${outputdir}:/out -v license.txt:/opt/freesurfer/license.txt:ro nipreps/nibabies:24.1.0 /data /out participant --participant-label ${subID} --output-spaces T2w fsaverage --anat-only --reference-anat T2w --bold2anat-init t2w --ignore fieldmaps t1w

What version of NiBabies are you using?

24.1.0
