first find out FAR and FRR.........

and ROC curve is given between FAR and GAR (Genuine Accept Rate)....

GAR = 100-FRR

We developped a webtool to easily analyze all sort of screening results, using all usual metrics in the field. You can generate ROC curves and more very quickly from your browser, see http://stats.drugdesign.fr (not so useful for large multi targets benchmarks though). Details on the calculation of ROC curves and other metrics can be found in the associated publications.
