Mass
difference

called Mass

Shifts all peak labels by the value entered (either positive or
negative) and can be used to calculate mass differences from a
reference peak.
Right-click-drag across the reference peak to enter the negative of
the value of the peak in the Mass difference text box, then click OK.
The reference peak is labeled with zero, and all the other labels are
plus or minus their mass difference from the reference peak.
This label is useful to display neutral losses and adducts on a given
peak.

adjacent
peaks
Labels peaks with a mass relative to the adjacent labeled peak of
lower m/z.
