S/N with Empower

[cholas]

I would like to create a custom field at empower to calculate the S/N, but I have no idea how can I do this. The S/N formula is : S/N= Peak height of the analyte expressed in mm/ Average peak-to-peak noise measurement from the baseline expressed in mm.
Any help will be appreciated
