ngsearch — find NGS datasets across every archive

Search millions of next-generation sequencing datasets across SRA/INSDC, GEO, ArrayExpress, GSA (NGDC) and CNSA in a single query — roughly 905,000 studies and 45 million samples. Filter by species, assay and tissue, search within a study down to individual samples, then export a ready-to-run download script.

Archives indexed

• SRA / INSDC — sequencing runs, experiments and samples
• GEO — series, samples and processed supplementary files
• ArrayExpress — functional genomics experiments
• GSA (NGDC) and CNSA — Chinese archives whose data never mirrors to SRA
