MetaHQ: Harmonized, high-quality metadata annotations of public omics samples and studies.

MetaHQ harmonizes standardized metadata for public omics, covering >567k samples and >27k studies in GEO from 13 sources.

• Why it matters: Free-text metadata and fragmented, differently formatted curation make it hard to locate relevant samples and combine annotations across resources.
• What they did: The team built a harmonized annotation database and released a Python command-line interface that queries the database and retrieves annotations.
• The result: MetaHQ enables integrated, standardized metadata access for GEO collections, supporting more effective discovery and reuse of public omics data.
