Extracts methylation levels from Bismark-aligned bisulfite sequencing data to generate per-cytosine reports.
This skill provides specialized guidance for performing methylation calling on Bismark-aligned BAM files. It facilitates the extraction of per-cytosine methylation reports across various genomic contexts (CpG, CHG, and CHH) for both single-end and paired-end sequencing data. Users can generate bedGraph files for genome browser visualization, comprehensive coverage reports for downstream analysis in tools like methylKit, and conduct M-bias analysis to identify and mitigate systematic biases in methylation measurements.
