Wellcome Sanger Institute Configuration
To use, run the pipeline with -profile sanger. This will download and launch the sanger.config which has been
pre-configured with a setup suitable for the Wellcome Sanger Institute LSF cluster.
Running the workflow on the Wellcome Sanger Institute cluster
The latest version of Nextflow is not installed by default on the cluster. You will need to install it into a directory you have write access to
- Install Nextflow : here
A recommended place to move the nextflow executable to is ~/bin so that it’s in the PATH.
Nextflow manages each process as a separate job that is submitted to the cluster by using the bsub command.
If asking Nextflow to use Singularity to run the individual jobs,
you should make sure that your account has access to the Singularity binary by adding these lines to your .bashrc file
[[ -f /software/modules/ISG/singularity ]] && module load ISG/singularityNextflow shouldn’t run directly on the submission node but on a compute node.
To do so make a shell script with a similar structure to the following code and submit with bsub < $PWD/my_script.sh
#!/bin/bash
#BSUB -o /path/to/a/log/dir/%J.o
#BSUB -e /path/to/a/log/dir/%J.e
#BSUB -M 8000
#BSUB -q oversubscribed
#BSUB -n 2
