About this guide
This is a guide outlining how to set up and execute the ONTViSc pipeline on three high-performance computing systems hosted by Australian research and computing facilities: Lyra (Queensland University of Technology), Gadi (National Computational Infrastructure) and Setonix (Pawsey). Throughout this guide we will make use of the Australian Nextflow Seqera Service provided to the researchers by Australian BioCommons.
ONTViSc (ONT-based Viral Screening for Biosecurity)
ONTViSc is a Nextflow-based bioinformatics pipeline designed to help diagnostics of viruses and viroid pathogens for biosecurity. It takes fastq files generated from either amplicon or whole-genome sequencing using Oxford Nanopore Technologies as input. The pipeline can either: 1) perform a direct search on the sequenced reads, 2) generate clusters, 3) assemble the reads to generate longer contigs or 4) directly map reads to a known reference. The reads can optionally be filtered from a plant host before performing downstream analysis.
