Displaying results The results of the calculation are displayed in the Elemental
Target tab of the Output window (Figure 6-21).

Results include:
• Index—Sequential number assigned to each result.
• Formula—Elemental composition you entered.
• m/z—Mass/charge of an observed peak that, compared
to the theoretical mass of the formula specified, is within
the Mass Tolerance and Resolution you specified.
• Charge—Charge of the observed peak.
• Isotope Match Score—Number between 0.0 and 1.0
that reflects how well the observed peak matches the
theoretical formula, based on mass and isotope pattern.
A higher number represents a better match.
• Isotope Match Intensity—Peak area (counts) that
overlaps between the observed isotope pattern and the
theoretical isotope pattern. A higher number represents a
better match.

distribution
To display the theoretical isotope distribution for a formula,
double-click the line in the Elemental Target tab of the Output
window.
The theoretical isotope trace is displayed in the Spectrum
window with an ISO trace label and the elemental formula.
