Processes - Nextflow Workshop 2022

Nextflow processes are the basic computing primitive to execute tasks. In practice a Nextflow pipeline script is made by joining together different processes. Each process can be written in any scripting language that can be executed by the Linux platform (Bash, R, Python, Perl, etc.).
Any process can define one or more channels as input and output. The interaction between these processes, and ultimately the pipeline execution flow itself, is implicitly defined by these input and output declarations.
