SUMMARY: A combination of bisulfite treatment of DNA and high-throughput sequencing (BS-Seq) can capture a snapshot of a cell's epigenomic state by revealing its genome-wide cytosine methylation at single base resolution. Bismark is a flexible tool for the time-efficient analysis of BS-Seq data which performs both read mapping and methylation calling in a single convenient step. Its output discriminates between cytosines in CpG, CHG and CHH context and enables bench scientists to visualize and interpret their methylation data soon after the sequencing run is completed. AVAILABILITY AND IMPLEMENTATION: Bismark is released under the GNU GPLv3+ licence. The source code is freely available from www.bioinformatics.bbsrc.ac.uk/projects/bismark/.
摘要:通过对 DNA 进行亚硫酸氢盐处理和高通量测序(BS-Seq)的组合,可以在单个碱基分辨率上揭示其全基因组胞嘧啶甲基化,从而捕获细胞表观基因组状态的快照。Bismark 是一种灵活的工具,可用于高效分析 BS-Seq 数据,它可以在单个方便的步骤中执行读映射和甲基化调用。它的输出区分 CpG、CHG 和 CHH 环境中的胞嘧啶,并使基础科学家能够在测序运行完成后立即可视化和解释他们的甲基化数据。
