Search and explore genomics databases

Search and filter ENCODE genomics experiments by assay/organ/target

Discovering existing ENCODE experiments before downloading when exploring what data is available for a tissue/assay.

• · Search filters: assay_title, organ, biosample_type, target, organism

• · List of matching ENCODE experiments with metadata
• · Facet counts showing data availability

• · ENCODE REST API
• · encode_search_experiments tool
• · encode_get_facets tool

Internet access to ENCODE portal, familiarity with ENCODE controlled vocabulary

Invalid assay_title value (not in controlled vocabulary), empty results if filter too restrictive, >2400 results if too broad

• · Three-phase search strategy (explore → validate → refine)
• · Facet-first guidance to avoid empty searches
• · Controlled vocabulary validation
