Hello World Pipeline

A modified version of the original hello world script from nextflow-io.

We test templates, passing files across processes, docker, local/cluster executions.

Description

4 processes, each of them appends a line (in a different language) to a file consumed by the next process. At the end of the execution, the content of the final file is shown.

Execution

Clone the project and run:

nextflow run main.nf -profile [local|cluster] 

or with pipeline sharing, just run:

nextflow run manuelesimi/hello-nextflow 

Output

$ nextflow run manuelesimi/hello-nextflow
