Can't load the Volumetric cell data

[ShuleiWu]

I would like to use the built-in function ramanspy.datasets.volumetric_cells(cell_type='THP-1', folder=None) from this Python package to load the dataset. However, the downloaded raw dataset files have the .wip file extension, while the provided function can only load .mat files. I'm unsure how to proceed. I have attempted to convert the .wip files to .mat format, but it was unsuccessful.
