Nextflow Overview Nextflow is a workflow language and runtime for building reproducible, portable, scalable data pipelines. It is dominant in bioinformatics but works for any data-heavy computation. nf-core is a community curating production-grade Nextflow pipelines, reusable modules, and the tooling on top of Nextflow. Key ideas: - Dataflow programming : pipelines are tasks connected by channels . Nextflow infers execution order and parallelism from data dependencies — there is no explicit scheduler to write. - Write once, run anywhere : the same pipeline runs locally, on HPC (SLURM, SGE, LS…
