How can I change the default figure of merit?

Hi, ROOT experts!
When I have done the training work and got the figure of ‘Cut efficiencies and Optimized Cut Value’, I just wander how I can change the default figure of merit S/sqrt(S+B) to Punzi figure of merit signal_efficiency/(3/2 + sqrt(B)). The figure has been attached.

Hi,

To my knowledge the only FoM supported for this optimisation is statistical significance (S/sqrt(S+B)). If you want to use a custom metric you will have to do this manually (by using the Application interface to get the raw output values and calculating your metric from there).

Cheers,

Thank you, and I have done it manually, actually.:grinning:
