How to deal with an argument that can take multiple type?
The argument gs can take either a file either a number, so I gave it type string but I am not sure if that is the best way to handle it.

     - name: --gs
        alternatives: [-f, -g]
        description: |
          This option inform about the genome size in order to compute more statistics. 
          You can give the size in Nucleotide or directly the fasta file.
        type: string

I would split it into 2 arguments.
