Overview
BiocMAP is a pair of Nextflow-based pipelines for processing raw whole genome bisulfite sequencing data into Bioconductor-friendly bsseq objects in R.
The first BiocMAP module performs speedy alignment to a reference genome by Arioc, and requires GPU resources. Methylation extraction and remaining steps are performed in the second module, optionally on a different computing system where GPUs need not be available.
Diagram representing the “conceptual” workflow traversed by BiocMAP. Here some nextflow
processes
are grouped together for simplicity; the exact processes traversed are enumerated here. The red box indicates the FASTQ files are inputs to the pipeline; green coloring denotes major output files from the pipeline; the remaining boxes represent computational steps. Yellow-colored steps are optional or not always performed; for example, lambda pseudoalignment is an optional step intended for experiments with spike-ins of the lambda bacteriophage. Finally, blue-colored steps are ordinary processes which occur on every pipeline execution.
