+full length transcript models.  When none of these data sources are available,
+GRIT can be run by providing a candidate set of TES or TSS sites.  In
+addition, GRIT can merge in reference junctions and gene boundaries.  GRIT can
+also be run in quantification mode, where it uses a provided GTF file and just
+estimates transcript expression.")
