    **What it does**

    Predict cell doublets using a nearest-neighbor classifier of observed transcriptomes and simulated doublets. Works best if the input is a raw (unnormalized) counts matrix from a single sample or a collection of similar samples from the same experiment. This function is a wrapper around functions that pre-process using Scanpy and directly call functions of Scrublet(). 

    This is a wrapper around the Scanpy wrapper for Scrublet- see https://scanpy.readthedocs.io/en/docsearch/external/scanpy.external.pp.scrublet.html.
