nf-core/cageseq

Edit

Introduction

nf-core/cageseq is a bioinformatics analysis pipeline used for CAGE-seq sequencing data.

The pipeline takes raw demultiplexed fastq-files as input and includes steps for linker and artefact trimming (cutadapt), rRNA removal (SortMeRNA, alignment to a reference genome (STAR or bowtie1) and CAGE tag counting and clustering (paraclu). Additionally, several quality control steps (FastQC, RSeQC, MultiQC) are included to allow for easy verification of the results after a run.

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.

Quick Start

1. Install nextflow

2. Install either Docker or Singularity for full pipeline reproducibility (please only use Conda as a last resort; see docs)

3. Download the pipeline and test it on a minimal dataset with a single command:

   nextflow run nf-core/cageseq -profile test,<docker/singularity/conda/institute>

   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 either docker or singularity and set the appropriate execution settings for your local compute environment.

4. Start running your own analysis!

nextflow run nf-core/cageseq -profile <docker/singularity/conda/institute> --input '*_R1.fastq.gz' --aligner <'star'/'bowtie1'> --genome GRCh38

See usage docs for all of the available options when running the pipeline.

Documentation
