Area of Science:

  • Bioinformatics
  • Genomics
  • Epigenetics

Background:

  • DNA methylation is crucial for gene regulation, driving demand for advanced analytical tools.
  • Processing and visualizing DNA methylation data requires specialized statistical methods.

Purpose of the Study:

  • To introduce MethVisual, an R package for exploratory analysis and visualization of DNA methylation data.
  • To provide a comprehensive tool for bisulfite sequencing data analysis within the R/Bioconductor environment.

Main Methods:

  • Developed an R package, MethVisual, for DNA methylation data analysis.
  • Implemented functions for data import, alignment, quality control, and visualization (e.g., lollipop plots, co-occurrence displays).
  • Included statistical analyses such as summary statistics, clustering, and correspondence analysis.

Main Results:

  • MethVisual enables intuitive visualization and exploratory analysis of DNA methylation patterns.
  • The package supports various analysis steps, including quality control and statistical summaries.
  • It can be applied to other binarizable data types beyond DNA methylation.

Conclusions:

  • MethVisual is the first dedicated R/Bioconductor package for DNA methylation analysis, particularly for bisulfite sequencing data.
  • It facilitates integrated data analysis from diverse technological platforms within the R environment.
  • The package offers a valuable resource for researchers studying epigenetics and gene regulation.
