+     "@code{InferCNV} is used to explore tumor single cell RNA-Seq data to identify
+evidence for somatic large-scale chromosomal copy number alterations, such as gains
+or deletions of entire chromosomes or large segments of chromosomes.  This is done
+by exploring expression intensity of genes across positions of a tumor genome in
+comparison to a set of reference \"normal\" cells.  A heatmap is generated
+illustrating the relative expression intensities across each chromosome, and it
+often becomes readily apparent as to which regions of the tumor genome are
+over-abundant or less-abundant as compared to that of normal cells.")
