P3BSseq: parallel processing pipeline software for automatic analysis of bisulfite sequencing data.

Area of Science:

• Genomics
• Bioinformatics
• Computational Biology

Background:

• Bisulfite sequencing (BSseq) is a crucial technique for DNA methylation analysis.
• Current BSseq processing tools are often complex, resource-intensive, and fragmented.
• There is a need for streamlined and efficient BSseq analysis pipelines.

Purpose of the Study:

• To develop a parallel processing pipeline, P3BSseq, for automated and efficient BSseq data analysis.
• To address the computational demands and usability challenges of existing BSseq tools.
• To provide a user-friendly solution for the upstream analysis of BSseq reads.

Main Methods:

• Developed P3BSseq, a parallel processing pipeline for BSseq data.
• Implemented functionalities for read trimming, alignment, annotation, and quality assessment.
• Optimized parameters for various library types (directional, non-directional) and read formats (single-end, paired-end).
• Ensured compatibility with Whole Genome and Reduced Representation BSseq.

Main Results:

• P3BSseq offers fast and accurate analysis of BSseq reads.
• The pipeline significantly reduces running time and computational hardware requirements (memory and processing power).
• P3BSseq generates standardized output files, including BED methylome and NIH-standard reports.
• The tool is optimized for current and future extended BSseq read lengths.

Conclusions:

• P3BSseq provides a streamlined, user-friendly solution for BSseq upstream analysis.
• It outperforms existing BSseq mappers in terms of speed and resource efficiency.
• The pipeline requires only basic computational and next-generation sequencing knowledge, making it accessible to a wider research community.
