Press Shift + 6 to auto-detect peaks using these settings.

peakStartSlope: how steep the slope must be to call a peak start.

Once derivative goes < 0 => apex is reached.

peakEndSlope: how negative the slope can stay before we say the peak is done.

minSignalAboveBaseline: how close to baseline to consider the tail done.

minPeakArea: if the integrated area is below this, ignore the peak.
