Hello,
If you are using the Python API, you can use the select_rows() call against the "study" schema and the "Datasets" table.
The study.Datasets table will allow you to see all of the datasets for the specific study container you're looking at.
For more details on setting up a select_rows() call, please refer to the following example:
