Build a query across multiple datasets at once using harmonized metadata ontology. Metadata consists of properties, which describe each dataset’s entities, and their values. Entities are particular resources with UUIDs, such as files, cases, samples, and cell lines. Learn more about metadata for datasets.
Simply select the datasets you'd like to query on the Data Browser Landing page before starting your query. Currently, you can choose two harmonized datasets, TCGA GRCh38 and TARGET GRCh38 to perform a multiple dataset query.
