"WebbThe following tutorial describes a simple PCA-based method for integrating data we call ingest and compares it with BBKNN [Polanski19]. BBKNN integrates well with the Scanpy workflow and is accessible through the bbknn function. The ingest function assumes an annotated reference dataset that captures the biological variability of interest. " - Scrna seq batch correction
