Summary

The Seqera Executor plugin provides integration with Seqera Cloud for executing Nextflow tasks using Seqera's managed compute infrastructure.

Get Started

To use this plugin, add it to your nextflow.config:

plugins {
    id 'nf-seqera'
}

Configure the Seqera executor:

process {
    executor = 'seqera'
}

seqera {
    executor {
        region = 'eu-west-1'
        autoLabels = true
    }
}

tower {
    accessToken = '<SEQERA ACCESS TOKEN>'
}

Alternatively, set the access token via environment variable:

export TOWER_ACCESS_TOKEN='<YOUR ACCESS TOKEN>'

Examples

Running a workflow with the Seqera executor

nextflow.config:

plugins {
    id 'nf-seqera'
}

process {
    executor = 'seqera'
}

tower {
    accessToken = '<SEQERA ACCESS TOKEN>'
}

seqera {
    executor {
        region = 'eu-west-1'
    }
}

main.nf:

process HELLO {
    output:
    path 'hello.txt'

    script:
    '''
    echo "Hello from Seqera Cloud" > hello.txt
    '''
}

workflow {
    HELLO()
}

Using resource labels for cost tracking

seqera {
    executor {
        region = 'us-east-1'
        labels = [team: 'genomics', project: 'wgs-analysis']
        autoLabels = true
    }
}

Using the resource prediction model

seqera {
    executor {
        region = 'eu-west-1'
        predictionModel = 'qr/v1'
    }
}
