I have many multiple peak events/signals as shown in attached picture. I want to calculate area under each individual peaks (in green color). For all signals I have baseline current (in red color), current with respect to time points and start and end time point of peak.

You can integrate the signal and do necessary modification to get the area.

You can calculate area using either by trapz or polyarea. Read about them.
