Nextflow code example

Nextflow

Data-driven computational pipelines

Nextflow enables scalable and reproducible scientific workflows using
software containers. It allows the adaptation of pipelines written in
the most common scripting languages.

Its fluent DSL simplifies the implementation and the deployment of
complex parallel and reactive workflows on clouds and clusters.

Features

Nextflow is built around the idea that Linux is the lingua franca of
data science.

Fast prototyping

Nextflow allows you to write a computational pipeline by making it
simpler to put together many different tasks.

You may reuse your existing scripts and tools and you don't need to
learn a new language or API to start using it.

Reproducibility

Nextflow supports Docker and Singularity containers technology.

This, along with the integration of the GitHub code sharing platform,
allows you to write self-contained pipelines, manage versions and to
rapidly reproduce any former configuration.

Portable

Nextflow provides an abstraction layer between your pipeline's logic
and the execution layer, so that it can be executed on multiple
platforms without it changing.

It provides out of the box executors for GridEngine, SLURM, LSF, PBS,
Moab and HTCondor batch schedulers and for Kubernetes, Amazon AWS,
Google Cloud and Microsoft Azure platforms.

Unified parallelism

Nextflow is based on the dataflow programming model which greatly
simplifies writing complex distributed pipelines.

Parallelisation is implicitly defined by the processes input and
output declarations. The resulting applications are inherently
parallel and can scale-up or scale-out, transparently, without having
to adapt to a specific platform architecture.

Continuous checkpoints

All the intermediate results produced during the pipeline execution
are automatically tracked.

This allows you to resume its execution, from the last successfully
executed step, no matter what the reason was for it stopping.

Stream oriented

Nextflow extends the Unix pipes model with a fluent DSL, allowing you
to handle complex stream interactions easily.

It promotes a programming approach, based on functional composition,
that results in resilient and easily reproducible pipelines.

---------------------------------------------------------------------

Getting started

It can be used on any POSIX compatible system (Linux, OS X, etc).
Simply follow these three steps.

Check prerequisites

Java 11 or later is required

1
Make sure 11 or later is installed
on your computer by using the command:
java -version
Note: If you are having trouble installing or upgrading Java
check out our documentation here.

Set up

Dead easy to install

2
Enter this command in your terminal:
curl -s https://get.nextflow.io | bash
(it creates a file nextflow in the current dir)
Note: it can also be downloaded from GitHub or installed by using
Bioconda package manager.

Launch

Try a simple demo

3
Run the classic Hello world
by entering the following command:
./nextflow run hello
