and wait a couple minutes until it has scaled the data (once it says "RUNNING HYSS" you are far enough) 
which will say near the end..

(which in this particular case are not useful!)
Here R is <Fderiv-Fnative>/(2 <Fderiv+Fnative>), noise is <sigma>, 
signal is sqrt(<(Fderiv-Fnative)**2>-<sigma**2>), and S/N is the ratio of signal to noise.
All the best,
