Exclamation Detection of differentially methylated regions (DMRs)

metilene: Fast and sensitive calling of differentially methylated regions from bisulfite sequencing data

The detection of differentially methylated regions (DMRs) is a necessary prerequisite for characterizing different epigenetic states. We present a novel program, metilene, to identify DMRs within whole genome and targeted sequencing data with unrivaled specificity and sensitivity. A binary segmentation algorithm combined with a two-dimensional statistical test allows to detect DMRs in large methylation experiments with multiple groups of samples in minutes rather than days using off-the-shelf hardware. metilene outperforms other state-if-the-art tools for low coverage data, and can estimate missing data. Hence, metilene is a versatile tool to study the effect of epigenetic modifications in differentiation/development, tumorigenesis and systems biology on a global, genome-wide level. Whether in the framework of international consortia with dozens samples per group, or even without biological replicates, it produces highly significant and reliable results.
