Equal-weight species-calibrated score

mean(clip(matrix_value / species_positive_q99, 0, 1))

  • Each mapped gene is scaled by its 99th percentile among positive cells in the complete source-species H5AD.
  • The same 15 mapped genes and SP121 species calibration are used for every system.
  • The score is descriptive relative expression on a 0–1 scale.
