Cannot slice image objects; consider using img.slicer[slice] to generate a sliced image (see documentation for caveats) or slicing image array data with img.dataobj[slice] or img.get_fdata()[slice]

Hi. I'm currently using the the muscle_adipose_tissue pipeline and it works perfectly.
However, I run into some issues when trying to use the spine_muscle_adipose_tissue and liver_spleen_pancreas pipelines, they all give the same type error:

force_separate_z: None interpolation order: 0
Traceback (most recent call last):
  File ".../.Trash/Comp2Comp/comp2comp/spine/spine.py", line 135, in spine_seg
    img, seg = nnUNet_predict_image(

    raise TypeError(
TypeError: Cannot slice image objects; consider using `img.slicer[slice]` to generate a sliced image (see documentation for caveats) or slicing image array data with `img.dataobj[slice]` or `img.get_fdata()[slice]`

Are there any specific modifications needed for the DICOM files to run these pipelines?

@DrKrabs , thanks for trying C2C and your feedback. Are you passing in a single DICOM file? spine_muscle_adipose_tissue and liver_spleen_pancreas are 3D methods so require DICOM series. Let me know if this doesn't fix your issue.

DICOM series likes this?

Or a whole study with multiple series like this?

Still the same error.
