Apollo Datasets

Learn about Apollo Datasets, how they're constructed, and how to use them.

An Apollo license is required to use Apollo Datasets on the DNAnexus Platform. Org approval may also be required. Contact DNAnexus Sales for more information.

An Apollo Dataset is a DNAnexus record of type dataset. It contains both data and metadata, and describes how logical data structures (such as phenotypes and genotypes) relate to the physical layout of the underlying databases.

You can use a Dataset to combine different data types—such as phenotypic, clinical, genomic, or transcriptomic data—across multiple databases into a single, linked, and documented object. Each Dataset record also stores provenance information about how it was created.

This structure makes it easier to:

• Reuse data in the same or different experiments

• Model and share multi-omic datasets

• Scale to large projects (such as TCGA or UKB)

• Maintain data linkages and annotations for reproducibility

• Build tools using a predictable, well-documented framework

Example uses of a Dataset include:

• Cohort Browser

• Apollo apps

• Jupyter Notebooks
