**What it does**

CheckV is a fully automated command-line pipeline for assessing the quality of single-contig viral genomes, including identification of host contamination for integrated proviruses, estimating completeness for genome fragments, and identification of closed genomes.

There are 4 steps:

1. Remove host contamination on proviruses
   - Genes are first annotated as viral or microbial based on comparison to a custom database of HMMs
   -  CheckV scans over the contig (5' to 3') comparing gene annotations and GC content between a pair of adjacent gene windows
   -  This information is used to compute a score at each intergenic position and identify host-virus breakpoints
   -  Works best for contigs that are mostly viral

2. Estimate genome completeness

   - Proteins are first compared to the CheckV genome database using AAI (average amino acid identity)
   - After identifying the top hits, completeness is computed as a ratio between the contig length (or viral region length for proviruses) and the length of matched reference
   - A confidence level is reported based on the strength of the alignment
   - Generally, high- and medium-confidence estimates are quite accurate
   - Less frequently, your viral genome may not have a close match to the CheckV database; in these cases CheckV estimates the completeness based on the viral HMMs identified on the contig
   - Based on the HMMs found, CheckV returns the estimated range for genome completeness (e.g. 35% to 60% completeness), which represents the 90% confidence interval based on the distribution of lengths of reference genomes with the same viral HMMs

3.: Predict closed genomes

    - Direct terminal repeats (DTRs)
        - Repeated sequence of >20-bp at start/end of contig
        - Most trusted signature in our experience
        - May indicate circular genome or linear genome replicated from a circular template (i.e. concatamer)
    - Proviruses
        - Viral region with predicted host boundaries at 5' and 3' ends (see panel A)
        - Note: CheckV will not detect proviruses if host regions have already been removed (e.g. using VIBRANT or VirSorter)
    - Inverted terminal repeats (ITRs)
        - Repeated sequence of >20-bp at start/end of contig (3' repeat is inverted)
        - Least trusted signature
    - For all the methods above, CheckV also checks whether the contig is approximately the correct sequence length based on estimated completeness; this is important because terminal repeats can represent artifacts of metagenomic assembly

4. Summarize quality.

   - Based on the results of 1-3, CheckV generates a report file and assigns query contigs to one of five quality tiers (consistent with and expand upon the MIUViG quality tiers):

     - Complete
     - High-quality (>90% completeness)
     - Medium-quality (50-90% completeness)
     - Low-quality (<50% completeness)
     - Undetermined quality


Usage
.....


**Input**

- Viral contigs in fasta (or gz, bz2 compressed fasta).
- CheckV reference data

**Output**

- Quality Summary: Tabular file showing integrated results from the three main modules and should be the main output referred to.
- Complete genomes: Tabular overview of putative complete genomes identified.
- Viruses: Virus sequences
- Proviruses: Provirus sequences

Optional outputs:

- Completeness: detailed overview of how completeness was estimated
- Contamination:  detailed overview of how contamination was estimated
