Using the CLI

To run a DeltaTwin® with an input of type DeltaTwin® Drive Data :

Create a JSON file containing your desired input values

In the example below, the input “product” refers to a data file. To reference a Drive Data file, set the field ‘type’ to DriveData and fill in the ‘value’ field with the ID of the resource.

For example, the JSON input file for the band-extractor component will be :


{
  "product": {
      "type": "DriveData",
      "value": "the-id-of-the-resource"
    },
  "bandName": {
      "type": "string",
      "value": "B01"
  }
}

Save JSON file as `inputs.json`

Run `deltatwin run start band-extractor -i inputs.json`

To get the ID of a resource, you can :

use the command deltatwin drive resource list -f json ;
or from the UI, navigate to the desired Drive Data and see its details page to get its ID.
