+based on a previously undescribed RNA-seq alignment algorithm that uses
+sequential maximum mappable seed search in uncompressed suffix arrays followed
+by seed clustering and stitching procedure.  In addition to unbiased de novo
+detection of canonical junctions, STAR can discover non-canonical splices and
+chimeric (fusion) transcripts, and is also capable of mapping full-length RNA
+sequences.")
