• Take ndmg as an example: https://github.com/BIDS-Apps/ndmg/blob/master/boutiques/ndmg-docker-bids.json
• leverage the option parameter in the SparkBIDS constructor.
• for every option in option: if option is not in [ --skip-participants, or other spark bids option ] : assume that it is an option of the Boutiques tool. Search for the corresponding command-line-flag or id in boutiques inputs. If not found: raise an error; otherwise, pass the value to boutiques.
