Z-Screen pilot release: combinatorial chemistry-to-transcriptome canonical dataset and reproduction bundle (April 2026, pre-bioRxiv draft)

Pre-bioRxiv draft release. Canonical dataset and reproduction bundle for five draft preprints from the Z-Screen pilot (April 2026). 615,793 mRNA-seq profiles across 12 combinatorial libraries (142,187 novel compounds) and 4 cell lines, paired with imaging, plus per-paper analysis scripts. Posted publicly under silent launch to collect technical feedback before formal bioRxiv submission. See http://www.z-screen.com for layman summaries and PDFs.
