Cells were segmented at the FOV level, cropped at 150x150 px around the segmented centroid, and resized to 224x224. Per-FOV percentile normalisation was applied before quantisation to uint8.",

  "rai:dataLimitations": "Cells from one cell line (U2OS), one assay (Cell Painting), one consortium (JUMP-CP). Channel order is the standard JUMP order and should be confirmed against the upstream pipeline before use. Quantisation to uint8 was applied during tile extraction.",
  "rai:dataBiases": "Compound coverage follows the JUMP-CP Target2 + Compound plate design and is biased toward annotated chemical probes and drug-like molecules. Source (JUMP partner) is a known major covariate that should be controlled in evaluation.",
