Reproducing routine bioinformatics analysis is challenging owing to a 
combination of factors hard to control for. Nextflow is a flow management 
framework that uses container technology to insure efficient deployment and 
reproducibility of computational analysis pipelines. Third party pipelines can 
be ported into Nextflow with minimum re-coding. We used RNA-Seq quantification, 
genome annotation and phylogeny reconstruction examples to show how two 
seemingly irreproducible analyzes can be made stable across platforms when 
ported into Nextflow.
