%description
A workflow based on 'scTenifoldNet' to perform in-silico knockout
experiments using single-cell RNA sequencing (scRNA-seq) data from
wild-type (WT) control samples as input.  First, the package constructs a
single-cell gene regulatory network (scGRN) and knocks out a target gene
from the adjacency matrix of the WT scGRN by setting the gene’s outdegree
edges to zero. Then, it compares the knocked out scGRN with the WT scGRN
to identify differentially regulated genes, called virtual-knockout
perturbed genes, which are used to assess the impact of the gene knockout
and reveal the gene’s function in the analyzed cells.
