Read depth versus observed read density (see Fig. S 2 for an illustration) for cells sorted into different cell cycle stages (apoptotic (D), G1, G2, and S phase) via FACS using DAPI staining. Each panel represents a different library: T-47D is a cancer cell line, and A73044A and A90553C are libraries consisting of normal cells (GM18507 cell line/SA928). Models of expected read density for a given read depth based on a reference populations of cells sequenced with DLP+ are indicated in cyan. =75 is indicated by the red dashed line.
