Chromatogram Instructions

Load a MOMA GCMS run
Under "Data Viewers" menu, select "Chromatogram Viewer"
From Chromatogram viewer, click "Thumbnail" checkbox (calculation
takes time, so there will be a period of unresponsiveness)
Create a ZIC or cZIC trace with UI at bottom of window

The 'Z' denotes the thumbnail data, which keeps only the detected
peaks that fit within the data volume estimate. If a SIC or cSIC is
duplicated with the '+' and the duplicate is changed to a ZIC or cZIC
it will stay linked to the original SIC or cSIC when changing m/z.
NOTE: the linking is only one way ZIC -->
SIC, not SIC --> ZIC
Calculation Notes:

Each summed histogram from the GCMS has a stripped down thumbnail
counterpart, which is at most 74 detected peaks
If a detected peak has a FWHM < 1.5 or > 5.5 bins, it is rejected

Mass Scan Viewer Instructions

Under "Data Viewers" menu, select "Mass Scan Viewer"
Select a mass scan in the list on the left side of window
Click the "Math" popup menu, and select the "Fit All" checkbox

This plots the fitted peaks over the raw data

To list the details of all the peaks, click "Peaks" popup menu and
select the "Show List" checkbox

The cutoff can be altered from the default value of 74 peaks
with the "Peak Number Cutoff" field
The red horizontal line indicates the y-axis value that
corresponds to the cutoff
