The ELN's Data Dryad Launchpad can be accessed from the Navigation bar (Fig 1). The launchpad allows users to generate Data Dryad (External Link) datasets, update them, and easily upload files attached to their relevant ELN pages directly to Dryad.

The Data Dryad workflow is described in the following sections.

In order to submit data to Data Dryad, you must first obtain an API token from your Data Dryad account page. Upon activating the API account, you will see the ability to generate an API token at the bottom of the page, as shown in Fig 2. Upon generating a token, it will remain active/usable for 10 years. After 10 hours, the user will need to get a new token.

Deleting Data Dryad datasets can only be done indirectly, i.e., they cannot be deleted through the ELN launchpad. This is because Data Dryad's API does not document a DELETE route to delete datasets. However, you can still delete datasets from your ELN by performing the following sequence of actions:

1. Delete the dataset on Data Dryad's website
2. Click the 'Delete from LIMS' button on the dataset's display card in the ELN

You must perform these steps in order. If you attempt to delete from the LIMS and ELN before deleting from Data Dryad, you will receive an error message telling you the operation is not allowed. This happens because, in order to try to maintain as much synchronicity as possible, the 'Delete from LIMS' step first checks whether the dataset still exists in Dryad. If it does, an error message is returned, telling the user that they must first delete the dataset from the Dryad website before further action can be taken.

Dryad files, like Dryad datasets, cannot be deleted through Data Dryad's API and must therefore be deleted from the Dryad website itself. However, as of April 6 2026, unlike Dryad datasets, there is no deletion mechanism for Dryad files in the LIMS. This will be remedied in a future update, and consequently, so will this section.
