A comparison of heat maps of selected gene classifiers. Heat maps were generated for gene classifiers of prochloraz-ovary and prochloraz-brain based on the corresponding gene expression profiles of the same chemical-tissue conditions in the respective training and validation datasets. All datasets were prepared tissue-specifically. The classifiers were unique to each chemical-tissue condition, and cross mapped between the design 015064 and 019161 based on the exact match of their probe sequences. The red and green bars above each heat map indicate treated and control samples in a condition. Pairs of heat maps in each column compare a classifier of the same group of gene features between the training and validation data. Pro, prochloraz; TF network, transcription factor network.
