+RNA-seq.  This statistical pipeline has been developed to identify and recover
+the base cycle profiles of oscillating genes in an unsynchronized single cell
+RNA-seq experiment.  The Oscope pipeline includes three modules: a sine model
+module to search for candidate oscillator pairs; a K-medoids clustering module
+to cluster candidate oscillators into groups; and an extended nearest
+insertion module to recover the base cycle order for each oscillator group.")
