You can display the following types of Voyager data by
selecting Extracted Ion from the Process menu with a
Chromatogram window displayed, then selecting:
Creating macros
to combine
processing
functions
You can create macros that perform multiple functions (for
example, smooth and baseline-correct), then start the macro
with one mouse click.
For information, see Section 6.7, Using the Macro Recorder.
Returning to the
original trace
Many processing functions generate a new trace. If you have
Trace Replace mode set to Replace, the new trace replaces
the original trace. For information on Replace mode, see
Section 2.4.4, Adding Traces from the Same Data File to a
Window.
To redisplay the original trace, select the trace type from the
Display menu or click the corresponding toolbar button.

(XIC)
Extracted Ion chromatogram, which includes only the response
from a mass window or range. For more information, see
Section 4.2.1, Creating an Extracted Ion Chromatogram (XIC).
Neutral Loss
(CNL)
Constant Neutral Loss Chromatogram, which extracts only the
response from a mass difference from a selected peak. For
more information, see Section 4.2.2, Creating a Constant
Neutral Loss (CNL) Chromatogram.
