+     "@dfn{Single-cell RNA-seq} (scRNA-seq) is widely used to investigate the
+composition of complex tissues since the technology allows researchers to
+define cell-types using unsupervised clustering of the transcriptome.
+However, due to differences in experimental methods and computational
+analyses, it is often challenging to directly compare the cells identified in
+two different experiments.  @code{scmap} is a method for projecting cells from
+a scRNA-seq experiment onto the cell-types or individual cells identified in a
+different experiment.")
