usage: nexus run --nf-workflow transcriptome_assembly_rnabloom2.nf [required] [optional] [--help]

required arguments:
    -c                                  :   Nextflow .config file.
    -w                                  :   Nextflow work directory path.
    --samples_tsv_file                  :   TSV file with the following columns:
                                            'sample_id', 'fastq_file'.
