nf-core/rnaseq

Edit

Introduction

nf-core/rnaseq is a bioinformatics analysis pipeline used for RNA sequencing data.

The workflow processes raw data from FastQ inputs (FastQC, Trim Galore!), aligns the reads (STAR or HiSAT2), generates counts relative to genes (featureCounts, StringTie) or transcripts (Salmon, tximport) and performs extensive quality-control on the results (RSeQC, Qualimap, dupRadar, Preseq, edgeR, MultiQC). See the output documentation for more details of 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.

Quick Start

i. Install nextflow

ii. Install one of docker, singularity or conda

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

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

iv. Start running your own analysis!

nextflow run nf-core/rnaseq -profile <docker/singularity/conda> --reads '*_R{1,2}.fastq.gz' --genome GRCh37

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