BAT

BAT processes bisulfite sequencing data to quantify DNA methylation and identify differentially methylated regions (DMRs).

Key Features:

• Read Alignment: Performs alignment of bisulfite-treated sequencing reads to reference genomes, mapping converted cytosine residues indicative of methylation status.
• Quality Control: Implements quality control measures to detect sequencing or alignment issues that could affect downstream methylation analyses.
• Extraction of Methylation Information: Extracts methylation calls from aligned reads to quantify methylation levels at specific genomic loci.
• Calling Differentially Methylated Regions (DMRs): Applies statistical methods to identify genomic regions with significant methylation differences between samples or conditions.
• Downstream Analyses: Integrates methylation data with gene expression, histone modification profiles, and transcription factor binding site annotations for functional interpretation.

Scientific Applications:

• Gene regulation and development: Facilitates analysis of how DNA methylation influences gene regulation and developmental processes.
• Disease and environmental studies: Supports investigation of methylation changes associated with disease progression and response to environmental factors.
• Integrative multi-omics analyses: Enables combined analysis of methylation with gene expression, histone modifications, and transcription factor binding to study genetic and epigenetic interplay.

Methodology:

Modular architecture implementing read alignment of bisulfite-treated reads, quality control, methylation extraction, DMR calling, and downstream integration, with modules optimized for performance on large bisulfite sequencing datasets.
