WebThe first step is to specify Q, the desired false discovery rate (either as a fraction between 0 and 1 or equivalently as a percentage between 0% and 100%). Prism then tells you which P values are low enough to be called a "discovery", with the goal of ensuring that no more than Q% of those "discoveries" are actually false positives. WebFalse discovery rate, or FDR, is defined to be the ratio between the false PSMs and the total number of PSMs above the score threshold.
