Quick overview

Nextflow is a bioinformatics workflow manager that enables the development of portable and reproducible workflows. It supports deploying workflows on a variety of execution platforms including local, HPC schedulers, AWS Batch, Google Cloud Life Sciences, and Kubernetes. Additionally, it provides support for manage your workflow dependencies through built-in support for Conda, Docker, Singularity, and Modules.

Rationale

With the rise of big data, techniques to analyse and run experiments on large datasets are increasingly necessary.

Parallelization and distributed computing are the best ways to tackle this problem, but the tools commonly available to the bioinformatics community often lack good support for these techniques, or provide a model that fits badly with the specific requirements in the bioinformatics domain and, most of the time, require the knowledge of complex tools or low-level APIs.

Nextflow framework is based on the dataflow programming model, which greatly simplifies writing parallel and distributed pipelines without adding unnecessary complexity and letting you concentrate on the flow of data, i.e. the functional logic of the application/algorithm.

It doesn't aim to be another pipeline scripting language yet, but it is built around the idea that the Linux platform is the lingua franca of data science, since it provides many simple command line and scripting tools, which by themselves are powerful, but when chained together facilitate complex data manipulations.

In practice, this means that a Nextflow script is defined by composing many different processes. Each process can execute a given bioinformatics tool or scripting language, to which is added the ability to coordinate and synchronize the processes execution by simply specifying their inputs and outputs.

Quick start

Download the package

Nextflow does not require any installation procedure, just download the distribution package by copying and pasting this command in your terminal:

curl -fsSL https://get.nextflow.io | bash

It creates the nextflow executable file in the current directory. You may want to move it to a folder accessible from your $PATH.

Download from Conda

Nextflow can also be installed from Bioconda

conda install -c bioconda nextflow

Documentation

Nextflow documentation is available at this link http://docs.nextflow.io

HPC Schedulers

Nextflow supports common HPC schedulers, abstracting the submission of jobs from the user.

Currently the following clusters are supported:

For example to submit the execution to a SGE cluster create a file named nextflow.config, in the directory where the pipeline is going to be launched, with the following content:

process {
  executor='sge'
  queue='
   
   
    
    '
   
   
}

In doing that, processes will be executed by Nextflow as SGE jobs using the qsub command. Your pipeline will behave like any other SGE job script, with the benefit that Nextflow will automatically and transparently manage the processes synchronisation, file(s) staging/un-staging, etc.

Cloud support

Nextflow also supports running workflows across various clouds and cloud technologies. Managed solutions from major cloud providers are also supported through AWS Batch, Azure Batch and Google Cloud compute services. Additionally, Nextflow can run workflows on either on-prem or managed cloud Kubernetes clusters.

Currently supported cloud platforms:

Tool management

Containers

Nextflow has first class support for containerization. It supports both Docker and Singularity container engines. Additionally, Nextflow can easily switch between container engines enabling workflow portability.

process samtools {
  container 'biocontainers/samtools:1.3.1'

  """
  samtools --version 
  """

}

Conda environments

Conda environments provide another option for managing software packages in your workflow.

Environment Modules

Environment modules commonly found in HPC environments can also be used to manage the tools used in a Nextflow workflow.

Community

You can post questions, or report problems by using the Nextflow discussion forum or the Nextflow channel on Gitter.

Nextflow also hosts a yearly workshop showcasing researcher's workflows and advancements in the langauge. Talks from the past workshops are available on the Nextflow YouTube Channel

The nf-core project is a community effort aggregating high quality Nextflow workflows which can be used by the community.

Build from source

Required dependencies

Compiler Java 8 or later
Runtime Java 8 or later

Build from source

Nextflow is written in Groovy (a scripting language for the JVM). A pre-compiled, ready-to-run, package is available at the Github releases page, thus it is not necessary to compile it in order to use it.

If you are interested in modifying the source code, or contributing to the project, it worth knowing that the build process is based on the Gradle build automation system.

You can compile Nextflow by typing the following command in the project home directory on your computer:

make compile

The very first time you run it, it will automatically download all the libraries required by the build process. It may take some minutes to complete.

When complete, execute the program by using the launch.sh script in the project directory.

The self-contained runnable Nextflow packages can be created by using the following command:

make pack

Once compiled use the script ./launch.sh as a replacement for the usual nextflow command.

The compiled packages can be locally installed using the following command:

make install

A self-contained distribution can be created with the command: make pack. To include support of GA4GH and its dependencies in the binary, use make packGA4GH instead.

IntelliJ IDEA

Nextflow development with IntelliJ IDEA requires the latest version of the IDE (2019.1.2 or later).

If you have it installed in your computer, follow the steps below in order to use it with Nextflow:

Clone the Nextflow repository to a directory in your computer.
Open IntelliJ IDEA and choose "Import project" in the "File" menu bar.
Select the Nextflow project root directory in your computer and click "OK".
Then, choose the "Gradle" item in the "external module" list and click on "Next" button.
Confirm the default import options and click on "Finish" to finalize the project configuration.
When the import process complete, select the "Project structure" command in the "File" menu bar.
In the showed dialog click on the "Project" item in the list of the left, and make sure that the "Project SDK" choice on the right contains Java 8.
Set the code formatting options with setting provided here.

Comments

Syntax enhancement aka DLS-2
This is a request for comments for the implementation of modules feature for Nextflow.

This feature allows the definition of NF processes in the main script or a separate library file, that can be invoked, one or multiple times, as any other routine passing the requested input channels as arguments.

Process definition

The syntax for the definition of a process is nearly identical to the usual one, it only requires the use of processDef instead of process and the omission of the from/into declarations. For example:

processDef index { tag "$transcriptome_file.simpleName" input: file transcriptome output: file 'index' script: """ salmon index --threads $task.cpus -t $transcriptome -i index """ }

The semantic and supported features remain identical to current process. See a complete example here.

Process invocation

Once a process is defined it can be invoked like any other function in the pipeline script. For example:

transcriptome = file(params.transcriptome) index(transcriptome)

Since the index defines an output channel its return value can be assigned to a channel variable that can be used as usual eg:

transcriptome = file(params.transcriptome) index_ch = index(transcriptome) index_ch.println()

If the process were producing two (or more) output channels the multiple assignment syntax can be used to get a reference to the output channels.

Process composition

The result of a process invocation can be passed to another process like any other function, eg:

processDef foo { input: val alpha output: val delta val gamma script: delta = alpha gamma = 'world' "some_command_here" } processDef bar { input: val xx val yy output: stdout() script: "another_command_here" } bar(foo('Hello'))

Process chaining

Processes can also be invoked as custom operators. For example a process foo taking one input channel can be invoked as:

ch_input1.foo()

when taking two channels as:

ch_input1.foo(ch_input2)

This allows the chaining of built-in operators and processes together eg:

Channel .fromFilePairs( params.reads, checkIfExists: true ) .into { read_pairs_ch; read_pairs2_ch } index(transcriptome_file) .quant(read_pairs_ch) .mix(fastqc(read_pairs2_ch)) .collect() .multiqc(multiqc_file)

See the complete script here.

Library file

A library is just a NF script containing one or more processDef declarations. Then the library can be imported using the importLibrary statement, eg:

importLibrary 'path/to/script.nf'

Relative paths are resolved against the project baseDir variable.

Test it

You can try to the current implementation using the version 19.0.0.modules-draft2-SNAPSHOT eg.

NXF_VER=19.0.0.modules-draft2-SNAPSHOT nextflow run rnaseq-nf -r modules

Open points

When a process is defined in a library file, should it be possible to access to the params values? Currently it's possible, but I think this is not a good idea because makes the library depending on the script params making it very fragile.

How to pass parameters to a process defined in library files eg. For example memory and cpus settings? It could be done using config file as usual, still I expect there could be the need to parametrise the process definition and specify the parameters at invocation time.

Should a namespace be used when defining the processes in library? What if two or more processes have the same name in different library files?

One or many processes per library file? Currently it can be defined any number of processes, I'm starting to think that it would be better to allow the definition only of one process per file. This would simplify the reuse across different pipelines, the import in tools such as dockstore and it would make the dependencies of the pipeline more intelligible.

Remote library file? Not sure it's a good idea to being able to import remote hosted files e.g. http://somewhere/script.nf. Remote paths tend to change over time.

Should a versioning number be associated with the process definition? how to use or enforce it?

How test process components? ideally it should be possible to include the required contained in the process definition and unit test each process independently.

How chain a process retuning multiple channels?

Nextflow parameter description scheme

TL;DR

A naming scheme to enable meta-data annotation for workflow parameters.

Details

Usually, workflow-specific execution parameters for the single processes are defined in the params scope, a DSL-feature Nextflow provides to access parameter variables from the workflow script during wf execution.

Currently, there is no naming scheme / convention / language feature for annotating parameters with description text, mandatory/optional flags or similar.

This could be useful though for upstream applications in order to build graphical user interfaces and configure a workflow correctly before execution in a dynamic, user-friendly way.

I am very happy for any input here and design suggestions :)

wr as new Nextflow backend
New feature

I develop wr which is a workflow runner like Nextflow, but can also just be used as a backend scheduler. It can schedule to LSF and OpenStack right now.

The benefit to Nextflow users of going via wr instead of using Nextflow’s existing LSF or Kubernetes support is:

wr makes more efficient use of LSF: it can pick an appropriate queue, use job arrays, and “reuse” job slots. In a simple test I did, Nextflow using wr in LSF mode was 2 times faster than Nextflow using its own LSF scheduler.

wr’s OpenStack support is incredibly easy to use and set up (basically a single command to run), and provides auto scaling up and down. Kubernetes, by comparison, is really quite complex to get working on OpenStack, doesn’t auto scale, and wastes resources with multiple nodes needed even while no workflows are being operated on. I was able to get Nextflow to work with wr in OpenStack mode (but the shared disk requirement for Nextflow’s state remains a concern).

Usage scenario

Users with access to LSF or OpenStack clusters who want to run their Nextflow workflows efficiently and easily.

Suggest implementation

Since I don’t know Java well enough to understand how to implement this “correctly”, I wrote a simple bsub emulator in wr, which is what my tests so far have been based on. I submit the Nextflow command as a job to wr, turning on the bsub emulation, and configure Nextflow to use its existing LSF scheduler. While running under the emulation, Nextflow’s bsub calls actually call wr.

Of course the proper way to do this would be have Nextflow call wr directly (either the wr command line, or it’s REST API). The possibly tricky thing with regard to having it work in OpenStack mode is having it tell wr about OpenStack-specific things like what image to use, what hardware flavour to use, pass details on how to mount S3 etc. (the bsub emulation handles all of this).

Here's what I did for my LSF test...

echo_1000_sleep.nf:

#!/usr/bin/env nextflow num = Channel.from(1..1000) process echo_sleep { input: val x from num output: stdout result "echo $x && sleep 1" } result.subscribe { println it } workflow.onComplete { println "Pipeline completed at: $workflow.complete" println "Execution status: ${ workflow.success ? 'OK' : 'failed' }" }

nextflow.config:

process { executor='lsf' queue='normal' memory='100MB' }

install wr:

wget https://github.com/VertebrateResequencing/wr/releases/download/v0.17.0/wr-linux-x86-64.zip unzip wr-linux-x86-64.zip mv wr /to/somewhere/in/my/PATH/wr

run:

wr manager start -s lsf echo "nextflow run ./echo_1000_sleep.nf" | wr add --bsub -r 0 -i nextflow --cwd_matters --memory 1GB

Here's what I did to get it to work in OpenStack...

nextflow_install.sh:

sudo apt-get update sudo apt-get install openjdk-8-jre-headless -y wget -qO- https://get.nextflow.io | bash sudo mv nextflow /usr/bin/nextflow

put input files in S3:

s3cmd put nextflow.config s3://sb10/nextflow/nextflow.config s3cmd put echo_1000_sleep.nf s3://sb10/nextflow/echo_1000_sleep.nf

~/.openstack_rc:

[your rc file containing OpenStack environment variables downloaded from Horizon]

run:

source ~/.openstack_rc wr cloud deploy --os 'Ubuntu Xenial' --username ubuntu echo "cp echo_1000_sleep.nf /shared/echo_1000_sleep.nf && cp nextflow.config /shared/nextflow.config && cd /shared && nextflow run echo_1000_sleep.nf" | wr add --bsub -r 0 -o 2 -i nextflow --memory 1GB --mounts 'ur:sb10/nextflow' --cloud_script nextflow_install.sh --cloud_shared

The NFS share at /shared created by the --cloud_shared option is slow and limited in size; a better solution would be to set up your own high performance shared filesystem in OpenStack (eg. GlusterFS), then add to nextflow_install.sh to mount this share. Or even better, is there a way to have Nextflow not store state on disk? If it could just query wr for job completion status, that would be better.

Introduce HTTP POST feature and broadcast workflow process runtime information
Motivation I thought it would be super cool to have a mechanism to let Nextflow send trace reports from the workflow processes during workflow execution, so one can monitor the workflow status and process on remote target sites (Webportals, API webservice with database logging, etc.).

This idea was already mentioned here https://github.com/nextflow-io/nextflow/pull/454 by @mes5k, but using websockets instead. Websockets are a lot more complex as they are stateful and one would need to be very careful with the implementation not to brake workflow execution. So I desided to go for simple HTTP POST requests, and it is the task of the user to provide a webserver, that consumes the information (JSON).

Mechanism I introduced a -with-messages option, that will trigger this functionality. You can specify the url in a messages-scope:

messages { // example URL url = "http://api.myserver.com/workflow/monitor" }

The logic is contained in the MessageObserver class analogous to the other observers, implementing the interface TraceObserver. HTTP POST requests will send a JSON object with information during the following Nextflow execution steps:

onFlowStart() - when the workflow starts

onFlowComplete() - when the workflow is completed

onProcessSubmit() - when a process is submitted

onProcessStart() - when a process starts

onProcessComplete() - when a process is completed

and new:

onFlowError() - which is invoked now in all observers when the Nextflow session catches an error.

For the latter, I observed, that the TaskHandler object was always null, even when I changed the error strategy to 'finish', which should call Session.cancel(handler) and not Session.abort(task.error). For that I had to change two lines of code https://github.com/nextflow-io/nextflow/commit/8104f6d5ccde600396dfa260eeda0e73a9e69b87, hope that is OK.

Information send via HTTP A JSON object with the following structure:

{ "runName": "<Nextflow run name>", "runID": "<Nextflow run ID>", "runStatus": "<started|running|error|completed>", "trace": "<Nextflows trace record>" }

Note: The "trace": "<Nextflows trace record>" entry is NOT present when onFlowStart() and onFlowComplete() are invoked. When present, "trace" contains all information showed in the Nextflow documentation.

As this is my first PR here, critically remark my code and I am happy for feedback!

Workflow report should warn if some task executions were ignored
It would be great if the Workflow Report (and other things) could warn if there were tasks that failed but were ignored. To do this, it would great to have variables with the counts of different task outputs. For example:

workflow.task_counts.success workflow.task_counts.cached workflow.task_counts.failed workflow.task_counts.ignored

..or whatever makes sense.

There can be some complication with tasks that fail but are resubmitted and succeed, but I guess if we can just count the ignored ones then we should be fine (we will get a pipeline error if something fails properly).

Thanks!

Completed jobs are detected with a big delay
Bug report

After job status transitions to SUCCEEDED (maybe also FAILED) within AWS batch, this status update is delayed available (hours) to nextflow as COMPLETED.

Expected behavior and actual behavior

nextflow job status update should be very close to the AWS Batch job transition.

Program output

See attached screenshot of the S3 workdir bucket contents.

This is the matching nextflow log output.

slow job submission with awsbatch executor

I would like to submit >20000 jobs (one per each file in a S3 bucket) for parallel processing.

In average nextflow submission to awsbatch only creates ~1 job per second to awsbatch which is too slow for this kind of large scale szenario. Each files is processed within 5-30min. This means in a horizontal scaling that the overall processing time could be executed in ~30min (plus overhead for instance creation and reporting).

Inconsistency of memory usage values within the report and timeline
Bug report

Expected behavior and actual behavior

expected behavior

Whatever we look at the Tasks table in Raw values mode or Human readable mode we expect to read the exact same values for the memory usage if the decimal system is used. We also expect these values to be the same in the Timeline.

actual behavior

in the Memory usage plot from the report, the memory value reported is 1051574272 (raw value extracted from Plotly) and displayed as 1.052G in the boxplot

in the Tasks table from the report in the Raw values mode, the memory value reported in the field vmem is 1051574272 which is consistent the previous value in the plot

in the Tasks table from the report in the Human readable mode, the memory value reported in the field vmem is 1.1GB seems to be ~ 1051574272 x (1.024 x 1.024). This value should be 0.97935GB = 1051574272/(1024 x 1024 x 1024) if the binary unit is used. Same behavior holds for peak_vmem and allocated memory fields but not for rss and peak_rss.

in the Timeline, the memory displayed is 1002.9 MB which is ~ 1051574272/(1024 x 1024) = 1002.859375. This is correct if the binary unit is used.

It should be mentioned whether you use decimal or binary unit to display the memory usage.

Steps to reproduce the problem

Install the program stress: sudo apt-get install stress or sudo yum install stress

Create the following nextflow.nf script:

#!/usr/bin/env nextflow process TwoCpus4mn { cpus 1 memory '1 GB' """ /usr/bin/time -v stress -c 2 -t 15 -m 1 --vm-bytes 1000000000 """ }

Enhance process metrics to avoid usage of ps tool
Hi,

I am using Nextflow with Biocontainers, which are gaining increasing traction (link1, link2). Biocontainers use a minimal BusyBox. That caused issues with coreutils that were previously fixed in Issue #321. I am now noticing another error in the .command.err log for any process started by Nextflow that leverages a Biocontainer:

ps: bad -o argument 'state', supported arguments: user,group,comm,args,pid,ppid,pgid,tty,vsz,stat,rss

It doesn't seem to be critical as processes still complete successfully, but I wonder whether this could still be fixed to get full BusyBox/Biocontainers support?

add support for AWS_SESSION_TOKEN
There's a few issues floating around about this:

https://github.com/nextflow-io/nextflow/issues/1724

https://github.com/nextflow-io/nextflow/issues/2839

https://github.com/nextflow-io/nextflow/pull/1265

Figured I'd take a stab at implementing. Wrote a test, but also ran locally and verified that the session token actually works.

I did combine the AWS_ACCESS_KEY/AWS_SECRET_KEY and AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY creds cases. Sure, technically, it means someone could supply an invalid config and it might work. But also, it unifies the session token logic.

I didn't add this to the config options, because who's putting an ephemeral token in their nextflow config??

Truthfully, I believe we're on the wrong path, and that we should just let the AWS Java SDK resolve credentials. It is opinionated in how it resolves credentials. If we delegated, we wouldn't have to account for every weird possible way of specifying aws creds. Perhaps there's a good reason not to though.

Anyway, let me know what you think. I'd love to have this in.

Mark the GridTaskHandler as FusionAwareTask

Use the NXF_CHDIR variable as the common pattern to specify the job work directory instead of relying on grid-specific directives

When fusion execution is required, submit the job execution by creating an inline job wrapper piped via stdin special file, instead of creating a temporary launcher file

This feature for production usage requires #3513 or #3514

Add support for Fusion file system for Sarus containerised task
Context

The Fusion file system allows using S3-compatible object storage as the task work directory.

This feature requires mounting the Fusion driver in the container process via a Fuse device.

When using Docker or Podman this can be achieved using the following options

--device /dev/fuse --cap-add SYS_ADMIN

See #3337 for details.

Goal

The goal of this feature is to allow the use of Fusion driver in containers run via the Sarus container engine.

xvfb-run waits forever when used in a nextflow process
Bug report

Expected behavior and actual behavior

We wanted to use xvfb-run igv !{batch_file} to allow igv to create a snapshot of an event on a headless AWS instance. Expected behavior is that xvfb-run will create a virtual framebuffer and igv will use it to paint the snapshot. Actual behavior is that xvfb-run waits forever after creating the Xvfb server.

The reason is that Xvfb communicates back by sending SIGUSR1, which should kill a wait in xvfb-run. But nextflow traps (and ignores) USR1 in .command.run, which causes the wait to last forever.

Steps to reproduce the problem

This process file produces the problem, and it should do so with pretty much any input. (Provide a test case that reproduce the problem either with a self-contained script or GitHub repository)

Program output

Under normal circumstances there is NO output to stderr or stdout. If I call xvfb-run via bash -x, the last executed command is the exec command from this block

trap : USR1 (trap '' USR1; exec Xvfb ":$SERVERNUM" $XVFBARGS $LISTENTCP -auth $AUTHFILE >>"$ERRORFILE" 2>&1) & XVFBPID=$! wait || :

The wait command never ends.

Environment

Nextflow version: 22.04.0

Java version: 1.8.2

Operating system: ubuntu 18.04

Bash version: GNU bash, version 5.1.4(1)-release (x86_64-pc-linux-gnu)

Breaking changes

The container entrypoint is not overridden anymore with /bin/bash by Nextflow when using Local, Kubernetes and batch scheduler executors. This has been made for consistency with the AWS, Google and Azure Batch executors that do not set it either. Make sure the containers used in your pipeline use sh or bash as the default entry point. If you want to continue to use the old behaviour set the variable NXF_CONTAINER_ENTRYPOINT_OVERRIDE=true in the launch environment

The use of Conda environment defined in the process definition via the conda directive needs to be enabled in an explicit manner using either the CLI option -with-conda or using the config setting conda.enabled=true or setting environment variable NXF_CONDA_ENABLED=true. See https://github.com/nextflow-io/nextflow/pull/3073 for details.
