VERSO 1.23.0

## 1 Overview

VERSO is an algorithmic framework that processes variants profiles from viral samples, to produce phylogenetic models of viral evolution from clonal variants and to subsequently quantify the intra-host genomic diversity of samples. VERSO includes two separate and subsequent steps; in this repository we provide an R implementation of VERSO STEP 1.

## 2 Installing VERSO

The R version of VERSO can be installed from Bioconductor. To do so, we need to install the R packages VERSO depends on and the devtools package.

    if (!require("BiocManager", quietly = TRUE))
        install.packages("BiocManager")

    BiocManager::install("VERSO")
