Overview

About

Maintained by Abhik SarkarCRAN page ↗

DNA methylation is an important epigenetic process that regulates gene activity through chemical modifications of DNA without changing its sequence. 'OpEnCAMeO' is a organism based ensemble model for prediction of 4mC, 6mA and No methylation sites directly from DNA sequences. It combines multiple machine learning algorithms trained on Bacteria (Escherichia coli), Fungi (Saccharomyces cerevisiae) and Nematode (Caenorhabditis elegans) as reference models to deliver accurate predictions. This methodology is being inspired by the ensemble algorithm for methylation prediction developed by Sinha et al. (2025) doi:10.1101/2025.11.10.687509.

Install

R (CRAN)Ubuntu (r2u)

install.packages("OpEnCAMeO", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-opencameo

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make
