-if (!require("BiocManager", quietly = TRUE))
-    install.packages("BiocManager")

   This workflow runs DESeq2 on the output of the kallisto workflow
   and the metadata file.
   It runs an R script, deseq2.R, which ideally should be split into three sub scripts and accordingly three workflow steps
