Change raTio lines displayed during base line subtraction of non catalytic data. That should be done before doing the baseline subtraction.
During this base line subtraction, the difference between the data and the base line (the non-catalytic, faradic current) is integrated and plotted as a function of the potential (green dashed line). If several peaks appear in the potential range, this option would help you to define the base line such that the (known) stoichiometry is respected. Choices are : none, 1/2, 1/3-2/3, 1/4-3/4, 1/5-4/5, 2/5-3/5 or no change. E.g. using option 1/3-2/3, lines will be drown corresponding to 1/3 and 2/3 of the integrated charge. Any other choice could be added. Default is set to ``none''.
The screen capture below illustrates a (not that nice) baseline substration for FrdAB. Lines at 1/5 and 4/5 of the total faradaic capacity are plotted to make sure the area under the peak corresponding to the low potential FeS cluster will be 1/5 of the total charge (one electron for each of the 3 FeS and 2 electrons for the flavin).
