"In the reduce_dimensionality function, is the first parameter 'expression' the normalized data or the original count data?"

hi,
Thank you very much for developing the excellent tool SCORPLUS. I have a question regarding the reduce_dimensionality function: Is the first parameter, 'expression', supposed to be the normalized data or the original count data? looking forward to your reply.
Best wishes,
Liu
