Examples illustrating the new feature selection step. a The fold change in both platforms was larger than the within-phenotype variability and the correlation coefficient between platforms (ρ _true ) was high; b when phenotypic labels in part A were randomly resampled, the fold change in both platforms became negligible as compared to the within-phenotype variability and the correlation coefficient between platforms (ρ _random ) became low. c The fold change in both platforms was smaller than the within-phenotype variability and the correlation coefficient between platforms (ρ _true ) was low; d when phenotypic labels in part C were randomly resampled, the correlation coefficient (ρ _random ) was low
