WebJust as we set alpha as a threshold for the p-value to control the FPR, we can also set a threshold for the q-value, which is the FDR analog of the p-value. A p-value threshold (alpha) of 0.05 yields a FPR of 5% among all truly null features. A q-value threshold of 0.05 yields a FDR of 5% among all features called significant.
