          Three output files are produced, in the form of
              outputjoin : assembled paired reads
              outputun1 : unassembled reads_1
              outputun2 : unassembled reads_2
  
          If a barcode / mate-pairs file is also provided then the following
          additional files are output:
              outputjoin2
              outputun3
  
          If a verbose stitch length report (-r) is chosen to be written by the
          user then use a user specified filename.
