+     "StringTie is a fast and efficient assembler of RNA-Seq sequence
+alignments into potential transcripts.  It uses a novel network flow algorithm
+as well as an optional de novo assembly step to assemble and quantitate
+full-length transcripts representing multiple splice variants for each gene
+locus.  Its input can include not only the alignments of raw reads used by
+other transcript assemblers, but also alignments of longer sequences that have
+been assembled from those reads.  To identify differentially expressed genes
+between experiments, StringTie's output can be processed either by the
+Cuffdiff or Ballgown programs.")
