Abstract

BackgroundBisulfite sequencing is a popular method to analyze DNA methylation patterns at high resolution. A region of interest is targeted by PCR and about 20-50 subcloned DNA molecules are usually analyzed, to determine the methylation status at single CpG sites and molecule resolution.ResultsThe BISMA (Bisulfite Sequencing DNA Methylation Analysis) software for analysis of primary bisulfite sequencing data implements sequencing data extraction and enhanced data processing, quality controls, analysis and presentation of the methylation state. It uses an improved strategy for detection of clonal molecules and accurate CpG site detection and it supports for the first time analysis of repetitive sequences.ConclusionsBISMA works highly automated but still provides the user full control over all steps of the analysis. The BISMA software is freely available as an online tool for academic purposes for the analysis of bisulfite sequencing data from both unique and repetitive sequences http://biochem.jacobs-university.de/BDPC/BISMA/.

Highlights

  • Bisulfite sequencing is a popular method to analyze DNA methylation patterns at high resolution

  • The Bisulfite Sequencing DNA Methylation Analysis (BISMA) software is designed for upload of primary bisulfite sequencing datasets derived after subcloning of PCR products from unique and repetitive sequences

  • The BISMA software supports the analysis of subcloned PCR products from bisulfite sequencing experiments
