Precision of prediction. Panel A shows the percentage of genes predicted within specific thresholds from 2 to 7 jumps from the source gene. The predicted value of each gene is defined as the average predicted values from source gene to target gene across different paths. If the actual expression value of a gene is +/- 20% the predicted value, then the gene is considered to be predicted within 20% threshold. The network coverage from 392 source genes (see Figure 3) is shown. Panel B shows the difference in prediction precision between the current set of microarray with 19.19% intra-slide variation and a set of theoretically consistent microarray with no intra-slide variation.
