When there are GDS IDs (e.g., 200069227) without Pubmed IDs, the
lengths of $ds->get_submitted_ids and $ds->get_ids will be different.
In this the pair information will be lost. How to keep the pair
information? (I am not sure if this is addressed in the cookbook.)

The above should be GDS IDs.

The above should be Pubmed IDs.
