Description: Whole genome single-cell DNA sequencing (scDNA-seq)
        enables characterization of copy number profiles at the
        cellular level. This circumvents the averaging effects
        associated with bulk-tissue sequencing and has increased
        resolution yet decreased ambiguity in deconvolving cancer
        subclones and elucidating cancer evolutionary history.
        ScDNA-seq data is, however, sparse, noisy, and highly variable
        even within a homogeneous cell population, due to the biases
        and artifacts that are introduced during the library
        preparation and sequencing procedure. Here, we propose SCOPE, a
        normalization and copy number estimation method for scDNA-seq
        data. The distinguishing features of SCOPE include: (i)
        utilization of cell-specific Gini coefficients for quality
        controls and for identification of normal/diploid cells, which
        are further used as negative control samples in a Poisson
        latent factor model for normalization; (ii) modeling of GC
        content bias using an expectation-maximization algorithm
        embedded in the Poisson generalized linear models, which
        accounts for the different copy number states along the genome;
        (iii) a cross-sample iterative segmentation procedure to
        identify breakpoints that are shared across cells from the same
        genetic background.
