Introduction

nf-core/methylseq is a bioinformatics best-practice analysis pipeline used for Methylation (BS-Seq) data analysis.

The pipeline uses Nextflow, a bioinformatics workflow tool. It pre-processes raw data from FastQ inputs, aligns the reads and performs extensive quality-control on the results.

Pipeline Steps

The pipeline allows you to choose between running either Bismark or bwa-meth / MethylDackel. Choose between workflows by using --aligner bismark (default) or --aligner bwameth.
