 Canu is a fork of the Celera Assembler, designed for high-noise single-molecule
 sequencing (such as the PacBio RS II/Sequel or Oxford Nanopore MinION).
 
 Canu is a hierarchical assembly pipeline which runs in four steps:
 
     Detect overlaps in high-noise sequences using MHAP
 
     Generate corrected sequence consensus
 
     Trim corrected sequences
 
     Assemble trimmed corrected sequences
