Thumbnail Contains a small picture of the chemical image and its associated
analysis and search information for each generated profile (or for each
found component for the MCR profile). All generated profile
thumbnails are displayed in the
profiles pane . The analysis
information includes the profile type and key profile settings.
Click the Results button in the thumbnail to see search results for the
spectrum at the current cursor location in the chemical image (or for
the selected pure component spectrum for the MCR profile).
Use Select Libraries to select the libraries to search.
Chemical image A scan that contains one spectrum collected at each sampling point in
a selected region of the displayed mosaic. The number and locations of
the spectra that make up the chemical image are defined by the
Image
pixel size setting. The number of passes is defined by the Number of
scans setting. A mathematical algorithm (defined by the Profile
settings ) is applied to each spectrum to create the chemical image. The
colors in the chemical image are determined by the profile intensity
scale .
Mosaic An image comprised of static pictures of the sample surface. The
pictures are stitched together with the edges slightly overlapped to
ensure that all areas are captured. The mosaic is created in the
OMNICxi Acquisition window and appears in the mosaic pane. It
also appears in the mosaic pane of the Analysis window.
Mosaic pane Shows any collected mosaics. Any regions of acquired chemical image
data are overlaid on top of the mosaic.
Right-click the mosaic pane for these options for copying and saving
data:
• Extract spectra from all frames of a region . Displays all the
spectra at the clicked point from all the time-based collect frames.
For example, if you have five time frames, click once with the
spectrum tool to display the five spectra.
• Delete Selected Region (or Delete All Regions ). Deletes selected
(or all) regions of acquired chemical image data.
• Crop frames from region. Allows removal of frames from either
end of a multiple-frame file. This option is not available on
recently collected data. It is only available for data opened from a
file. Note that the trim function immediately and irreversibly
deletes the trimmed data from the file.
