python3 setup.py install

# correct contigs
ragtag.py correct ref.fasta query.fasta

# scaffold contigs
ragtag.py scaffold ref.fa ragtag_output/query.corrected.fasta

Dependencies

• Minimap2 or Nucmer
• Python 3 (with the following auto-installed packages)
  • numpy
  • intervaltree
  • pysam

Acknowledgments

Many of the major algorithmic improvements relative to RaGOO's first release were provided by Aleksey Zimin, lead developer of the MaSuRCA assembler. This includes the use of read-mapping for misassembly validation as well as the use of alignment merging for improved scaffolding. Luca Venturini also suggested and initially implemented many feature enhancments, such as pysam integration.
