+sequencing data.  It detects @dfn{differentially expressed genes} (DEGs) from
+RNA-seq, and differentially methylated loci or regions (DML/DMRs) from
+@dfn{bisulfite sequencing} (BS-seq).  The core of DSS is a dispersion
+shrinkage method for estimating the dispersion parameter from Gamma-Poisson or
+Beta-Binomial distributions.")
