Peak Detection
Max Isotope #
If the Max Isotope # is set too low, the software incorrectly
groups peaks into different isotope clusters. In this example
set too low
with the Max Isotope # set to 2 and Max Charge State set to 4,
the software labels all peaks as charge state 3 (Figure 3-10).

State Set Correctly

The effect of setting Max Isotope # too low is apparent when
you turn on Monoisotopic peak list filtering. Figure 3-11 shows
that the software has grouped the peaks into two clusters and
has identified two monoisotopic peaks.
