BSBolt

BSBolt performs processing of bisulfite sequencing data to produce analysis-ready DNA methylation calls and methylation matrices for quantitative DNA methylation measurement.

Key Features:

• Integrated analysis suite: Provides simulation, alignment, methylation calling, data aggregation, and imputation to generate analysis-ready methylation matrices.
• Pre-alignment read assessment: Assesses reads prior to alignment to optimize mapping for asymmetrical bisulfite sequencing libraries and low-complexity sequences.
• Alignment and methylation calling: Performs alignment and methylation calling specifically for bisulfite sequencing data.
• Performance evaluation: Demonstrated superior alignment speed and methylation calling accuracy on simulated and real bisulfite sequencing datasets compared with Bismark, BSSeeker2, BISCUIT, and BWA-Meth.
• Protocol support: Validated for whole genome bisulfite sequencing (WGBS), reduced representation bisulfite sequencing (RRBS), and targeted methylation sequencing.

Scientific Applications:

• DNA methylation quantification: Produces accurate methylation calls for studies measuring cytosine methylation from bisulfite sequencing data.
• Epigenetics and genomics research: Enables characterization of methylation patterns relevant to gene regulation, developmental biology, and disease mechanisms.

Methodology:

Performs read simulation, pre-alignment read assessment, bisulfite sequencing alignment, methylation calling, aggregation into methylation matrices, and imputation; validated on simulated and real bisulfite sequencing datasets.
