Actual Behavior

/home/oesteban/.miniconda/lib/python3.9/site-packages/phys2bids/physio_obj.py:649: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray.
