The results from E-Predict follow similar patterns to those of DetectiV. In most cases it is obvious which virus is the infectious agent, either by examining the p value, the similarity or both together. Full results can be seen on the DetectiV website [15] . However, there are certain results reported by E-Predict where it is impossible to obtain the correct result no matter which combination of p value and similarity is used. These arrays are arrays are GSM40809, GSM40821 and GSM40847, and the top five results for these arrays can be seen in Table 5 .
