 The abundance of transcripts in a human tissue sample
 can be determined by RNA sequencing. The exact sequence
 sampled may be random, depending on the technology used.
 And it may be short, i.e. shorter than the transcript.
 At some point, many shorter reads need to be assembled
 to the model the complete transcripts.
 .
 StringTie knows how to assemble of RNA-Seq into potential
 transcripts without the need of a reference genome and
 provides a quantification also of the splice variants.
