Description: A common bioinformatics task in single-cell data analysis
        is to purify a cell type or cell population of interest from
        heterogeneous datasets. 'scGate' automatizes marker-based
        purification of specific cell populations, without requiring
        training data or reference gene expression profiles. Briefly,
        'scGate' takes as input: i) a gene expression matrix stored in
        a 'Seurat' object and ii) a “gating model” (GM), consisting of
        a set of marker genes that define the cell population of
        interest. The GM can be as simple as a single marker gene, or a
        combination of positive and negative markers. More complex GMs
        can be constructed in a hierarchical fashion, akin to gating
        strategies employed in flow cytometry. 'scGate' evaluates the
        strength of signature marker expression in each cell using the
        rank-based method 'UCell', and then performs k-nearest neighbor
        (kNN) smoothing by calculating the mean 'UCell' score across
        neighboring cells. kNN-smoothing aims at compensating for the
        large degree of sparsity in scRNA-seq data. Finally, a
        universal threshold over kNN-smoothed signature scores is
        applied in binary decision trees generated from the
        user-provided gating model, to annotate cells as either “pure”
        or “impure”, with respect to the cell population of interest.
