nf-core/methylseq
Methylation (Bisulfite-Sequencing) analysis pipeline using Bismark or bwa-meth + MethylDackel
1.6.1
). The latest
stable release is
2.6.0
.
Introduction
nf-core/methylseq is a bioinformatics analysis pipeline used for Methylation (Bisulfite) sequencing data. It pre-processes raw data from FastQ inputs, aligns the reads and performs extensive quality-control on the results.
The pipeline is built using Nextflow, a workflow tool to run tasks across multiple compute infrastructures in a very portable manner. It comes with docker containers making installation trivial and results highly reproducible.
Pipeline Summary
The pipeline allows you to choose between running either Bismark or bwa-meth / MethylDackel.
Choose between workflows by using --aligner bismark
(default, uses bowtie2 for alignment), --aligner bismark_hisat
or --aligner bwameth
.

Quick Start
-
Install
nextflow
-
Install any of
Docker
,Singularity
,Podman
,Shifter
orCharliecloud
for full pipeline reproducibility (please only useConda
as a last resort; see docs) -
Download the pipeline and test it on a minimal dataset with a single command:
Please check nf-core/configs to see if a custom config file to run nf-core pipelines already exists for your Institute. If so, you can simply use
-profile <institute>
in your command. This will enable eitherdocker
orsingularity
and set the appropriate execution settings for your local compute environment. -
Start running your own analysis!
See usage docs for all of the available options when running the pipeline.
Documentation
The nf-core/methylseq pipeline comes with documentation about the pipeline: usage and output.
