featurePlot             Detect the sgRNA distribution and generate
                        Vlnplot to identity gene regulation between
                        different cells.
pre_processRDS          Integrate the imformation of sgRNA into RDS
                        file for the further analysis.
scMAGeCK-package        Identify genes associated with multiple
                        expression phenotypes in single-cell CRISPR
                        screening data
scmageck_lr             Use linear regression to test the association
                        of gene knockout with all possible genes
scmageck_rra            Use RRA to test the association of gene
                        knockout with certain marker expression
selectPlot              generate the selection plot
