# Viral

## Apps

* [vContact2](https://kbase.us/applist/apps/vConTACT/vcontact/release): perform guilt-by-contig-association automatic classification of viral contigs
* [VirSorter2](https://kbase.us/applist/apps/kb_virsorter2/run_kb_virsorter2/release): Identifies viral sequences from viral and microbial metagenomes
  * VirSorter (legacy)
* [VirMatcher](https://narrative.kbase.us/#catalog/apps/kb_virmatcher/run_kb_virmatcher/release):  Predicts host-virus matches

## Input

The viral workflow begins with [Assemblies](https://docs.kbase.us/data/upload-download-guide/assembly), either metagenome or single genomes. VirSorter produces the assemblies that should be used by vContact as input.  

## Narratives

* [Viral Annotation Pipeline in KBase](https://doi.org/10.25982/59912.37/1635154) – a streamlined use case of a pre-assembled small metagenome and a Cyanophage genome run through VirSorter to identify viral sequences and vContact to classify them.
* [Viral Analysis End-to-End](https://doi.org/10.25982/75811.86/1868934) – a more comprehensive tutorial with a use case from the Global Ocean Virome demonstrating how to go through the entire process starting with raw metagenomic reads.
  * Tutorial Narratives were made available by Ben Bolduc of Ohio State University.
