## Workflow

### Job Creation

[Create a new job](/public/docs/jobs-overview#create-a-job) and select the `Empty Rack Creation` workflow.

### Requesting

- Select **File** as the Request From.
- Set Target Rack Barcode to **Use External Barcode**.
- Select **96 (96)** as the Rack Format.
- Click `Next`.

### Processing

- Upload the file named [barcodes.csv](https://cdn.document360.io/dde9293e-c107-4b3e-9774-9c9c296ed970/Images/Documentation/discngine-assay-barcodes.csv?sv=2026-02-06&spr=https&st=2026-11-11T11%3A27%3A29Z&se=2026-11-11T12%3A27%3A29Z&sr=c&sp=r&sig=cofP%2BDfhGQqQKUiN4ZRSQSYoW5I%2F29cYm9r5F7F7nY8%3D).
