MeStudio: crossing methylation and genomic features for comparative
epigenomic analyses
Abstract
DNA methylation is one of the most relevant epigenetic modifications. It
is present in eukaryotes and prokaryotes and is related to several
biological phenomena, including gene flow and adaptation to
environmental conditions. The widespread use of third-generation
sequencing technologies allows direct and easy detection of genome-wide
methylation profiles, offering increasing opportunities to understand
and exploit the epigenomics landscape of individuals and populations.
Here, we present MeStudio, a pipeline which allows to analyse and
combine genome-wide methylation profiles with genomic features. Outputs
report the presence of DNA methylation in coding sequences (CDS) and
noncoding sequences, including both intergenic sequences, and sequences
upstream to CDS. We show the usage and performances of MeStudio on a set
of single-molecule real time sequencing outputs from strains of the
bacterial species Sinorhizobium meliloti. MeStudio is freely available
