False prediction percentages for genes in particular cellular compartments (A) and particular metabolic subsystems (B). The overall error rate is the percentage of false predictions out of all of the predictions. The false-negative (FN) rate is the percentage of FN predictions out of all predictions in which the experimental data show normal growth. The false-positive (FP) rate is the percentage of FP predictions out of all predictions in which the experimental data show retarded growth. Genes that participate in transport functions between compartments are classified according to Table 2. Compartments with at least 10 genes and metabolic subsystems with at least 15 genes are included.
