All nf-core pipelines have been successfully configured for use on the tars cluster at the Institut Pasteur.
To use, run the pipeline with -profile pasteur. This will download and launch the pasteur.config which has been pre-configured with a setup suitable for the Pasteur cluster. Using this profile, a docker image containing all of the required software will be downloaded, and converted to a Singularity image before execution of the pipeline.
Nextflow is not installed by default on the Pasteur cluster.
- Install Nextflow : here
Nextflow manages each process as a separate job that is submitted to the cluster by using the sbatch command.
Nextflow shouldn't run directly on the submission node but on a compute node.
The compute nodes don't have access to internet so you need to run it offline.
To do that:
- Create a virtualenv to install nf-core
module purge
module load Python/3.6.0
module load java
module load singularity
cd /path/to/nf-core/workflows
virtualenv .venv -p python3
. .venv/bin/activate- Install nf-core: here
- Get nf-core pipeline and container: here
- Get the nf-core Pasteur profile: here
- Run nextflow on a compute node:
# create a terminal
tmux
# Get a compute node
salloc
# Load the dependencies if not done before
module purge
module load java
module load singularity
# Run nextflow workflow
nextflow run \\
