cluster of 4 large peaks with valley-to-valley baselines.

When the dialog box appears displaying the start and stop
points for the event, click the Analyze Now button and view
the chromatogram. Notice the peaks within the region of the
event are now integrated using the valley-to-valley event, and
baselines are adjusted accordingly.
