nf-core/sarek
Analysis pipeline to detect germline or somatic variants (pre-processing, variant calling and annotation) from WGS / targeted sequencing
2.7
). The latest
stable release is
3.5.0
.
Introduction
Sarek is a workflow designed to detect variants on whole genome or targeted sequencing data. Initially designed for Human, and Mouse, it can work on any species with a reference genome. Sarek can also handle tumour / normal pairs and could include additional relapses.
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.
It’s listed on Elixir - Tools and Data Services Registry and Dockstore.
Quick Start
-
Install
Nextflow
-
Install any of
Docker
,Singularity
orPodman
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/sarek pipeline comes with documentation about the pipeline: usage and output.
Credits
Sarek was developed at the National Genomics Infastructure and National Bioinformatics Infastructure Sweden which are both platforms at SciLifeLab, with the support of The Swedish Childhood Tumor Biobank (Barntumörbanken). QBiC later joined and helped with further development.
