Nextflow Feature Highlights: Syntax Parser, Native Data Lineage, and Workflow Outputs

At Nextflow Summit Boston 2025, Seqera CTO and co-founder Paolo Di Tomasso unveiled a series of exciting Nextflow updates as part of the 25.04 release, all designed to enhance clarity, control, and collaboration in workflow development. From stricter syntax and smarter workflow input/output handling to native provenance tracking, this release empowers developers with a more powerful, intuitive, and reproducible experience.

VIRUS-MVP: A scalable and flexible pathogen surveillance workflow powered by Nextflow and nf-core

VIRUS-MVP leverages Nextflow and nf-core to provide a modular, automated, and scalable framework for genomic surveillance of priority viruses. Designed initially for SARS-CoV-2, the workflow was later adapted or is in development for other priority viruses, including Mpox, respiratory syncytial virus (RSV), and influenza.

Automating SRA data access and processing with Nextflow

Handling large-scale genomic data efficiently is one of the most pressing challenges in bioinformatics. My work on pediatric gliomas requires processing vast amounts of RNA-seq data from publicly available repositories like the Sequence Read Archive (SRA). Traditional methods of handling these datasets involved labor-intensive manual downloads and data validation processes. This approach was time-consuming, error-prone, and lacked reproducibility. To address these issues, I developed biopy_sra.nf, a Nextflow pipeline designed to automate the process of accessing, downloading, and preprocessing RNA-seq data from SRA.

How Nextflow builds key software development skills for bioinformaticians

I first used Nextflow at 19 years old, a year out of school during the first year of my apprenticeship. Over the next 5 years, I acquired a diverse set of essential skills that enabled me to explore a wide range of career opportunities by building Nextflow pipelines.

Nextflow and Seqera containers: a lifesaver for bioinformatics work on HPC environments

In bioinformatics and data science, handling large datasets and dependencies is crucial. Nextflow, a powerful domain-specific language, enables efficient, reproducible workflows across local and cloud platforms. In this post, I share how Nextflow and Seqera Containers have revolutionized my work in the Oncology Data Science group at Novartis, Cambridge, MA, allowing us to optimize complex computational workflows seamlessly.

Nextflow workflow: from HPC to Cloud

Bioinformaticians often run their Nextflow workflows on internal HPC clusters, typically using job schedulers like Slurm to manage tasks. However, as the need for scalability and flexibility grows, many are making the shift to public cloud platforms. In this post, we'll highlight key details from a recent real-world example to demonstrate details about this process.

Daisy-chaining workflows: the nf-cascade concept

Nextflow workflows are widely used across various fields, performing tasks ranging from data retrieval and cleaning to processing and downstream analyses. Generally, workflows which feed into other workflows are run independently. They are also often not written in a way they can be included directly as subworkflows into another workflow, making it challenging to connect them seamlessly. nf-cascade is a proof-of-concept pipeline that demonstrates how multiple existing workflows can be integrated into a single workflow. Specifically, the proof-of-concept connects the nf-core pipelines: nf-core/fetchngs, nf-core/taxprofiler, nf-core/mag, and nf-core/funcscan. The code can be generalised further to run and connect any existing workflow, without any modifications necessary to the workflows you want to run.

My Journey with Nextflow: From Exploration to Automation

I approach bioinformatics workflows in a whole different way now that I’ve used Nextflow. It has evolved into a vital tool in my toolbox, capable of handling massive genomic datasets and guaranteeing repeatability and scalability. Thanks to Nextflow, I can automate and streamline tasks that used to take days or even weeks, whether it’s merging disparate software applications or simplifying intricate pipelines. To go beyond the constraints of conventional scripting (bash, perl, Python, R) for genomic data analysis was the driving force for my decision to work with Nextflow. Since then, it’s opened up new possibilities, leading me to collaborations, innovation, and now this exciting new role as an Ambassador! I am Pritam Kumar Panda, a bioinformatician working at the German Cancer Research Center DKFZ, Heidelberg, Germany.

Addressing Bioinformatics Core Challenges with Nextflow and nf-core

I was honored to be invited to the ISMB 2024 congress to speak at the session organised by the COSI (Community of Special Interest) of Bioinformatics Cores. This session brought together bioinformatics professionals from around the world who manage bioinformatics facilities in different institutions to share experiences, discuss challenges, and explore solutions for managing and analyzing large-scale biological data. In this session, I had the opportunity to introduce Nextflow, and discuss how its adoption can help bioinformatics cores to address some of the most common challenges they face.

Experimental cleanup with nf-boost

When I (Ben) was in grad school, I worked on a Nextflow pipeline called GEMmaker, an RNA-seq analysis pipeline similar to nf-core/rnaseq. We quickly ran into a problem, which is that on large runs, we were running out of storage! As it turns out, it wasn’t the final outputs, but the intermediate outputs (the BAM files, etc) that were taking up so much space, and we figured that if we could just delete those intermediate files sooner, we might be able to make it through a pipeline run without running out of storage. We were far from alone.

How I became a Nextflow Ambassador!

As a PhD student in bioinformatics, I aimed to build robust pipelines to analyze diverse datasets throughout my research.

Leveraging nf-test for enhanced quality control in nf-core

Reproducibility is an important attribute of all good science. This is especially true in the realm of bioinformatics, where software is hopefully being updated, and pipelines are ideally being maintained. Improvements and maintenance are great, but they also bring about an important question: Do bioinformatics tools and pipelines continue to run successfully and produce consistent results despite these changes? Fortunately for us, there is an existing approach to ensure software reproducibility: testing.

Analyzing caching behavior of pipelines

The ability to resume an analysis (i.e. caching) is one of the core strengths of Nextflow. When developing pipelines, this allows us to avoid re-running unchanged processes by simply appending -resume to the nextflow run command. Sometimes, tasks may be repeated for reasons that are unclear. In these cases it can help to look into the caching mechanism, to understand why a specific process was re-run.

Turbo-charging the Nextflow command line with Fig!

Nextflow is a powerful workflow manager that supports multiple container technologies, cloud providers and HPC job schedulers. It shouldn’t be a surprise that wide ranging functionality leads to a complex interface, but comes with the drawback of many subcommands and options to remember. For a first-time user (and sometimes even for some long-time users) it can be difficult to remember everything. This is not a new problem for the command-line; even very common applications such as grep and tar are famous for having a bewildering array of options.
