VirFind is an online virus discovery tool running on computer nodes housed at Arkansas High Performance Computing Center. It can:

  • Accept different input file formats including fasta and fastq.
  • Map the reads to reference genomes.
  • Perform de novo assembly to get longer contigs.
  • Filter out non-virus sequences that can create noise in the sequencing data.
  • Detect known viruses.
  • Discover new viruses.
  • Perform conserved domain search.
  • And give you sequences that are not yet determined if viral or not viral.

The tool is a set of different modules, each with a specific job, and future modules can be added for additional capabilities.
