+data collected from more than one subject (e.g. biological sample or technical
+replicates).  A @code{SingleCellExperiment} object is taken as input and
+converted to a list of @code{SummarizedExperiment} objects, where each list
+element corresponds to an assigned cell type.  The @code{SummarizedExperiment}
+objects contain aggregate gene-by-subject count matrices and inter-subject
+column metadata for individual subjects that can be processed using downstream
+bulk RNA-seq tools.")
