To use, run the pipeline with -profile janelia
. This will download and launch the janelia.config
which has been pre-configured with a setup suitable for the Janelia Research Campus LSF cluster.
The latest version of Nextflow is not installed by default on the cluster. You will need to install it into your cluster account by following the installation instructions:
Remember to move the nextflow
executable to ~/bin
or otherwise ensure that it's in your PATH
.
Nextflow manages each process as a separate job that is submitted to the cluster by using the bsub
command. Janelia's cluster has Singularity installed on all login and compute nodes, and the profile specifies that Singularity will be used to execute processes.
Nextflow should never be run directly on a login node. You can run it via an interactive cluster session (bsub -Is /bin/bash
), or make a wrapper shell script like the example below, 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 -n 2

You can use Janelia's internal Nextflow Tower instance to run workflows on the cluster. Additional instructions for using this resource can be found on the Janelia Wiki.
