The Analysis window can be used to analyze the same sample using different profile settings in
order to compare the results visually.
for more information.
Use the Spectrum tool to click a point in the acquired (or partially acquired) chemical image.
The spectrum collected at that time and location appears in the spectral pane. For the MCR
profile type, the calculated pure component spectrum associated with the current cursor
location is also displayed in the spectral pane.
To search the displayed spectrum against the available spectral libraries, click
. The search results window appears above the button. The name of the
best matched spectrum from the available spectral libraries appears at the top of the search
results window and its spectrum is added to the spectral pane. After you close the search
results window, the library spectrum disappears from the spectral pane.

Correlation Profile Settings
The Correlation profile shows the correlation between each sample point in the chemical
image and the current reference spectrum. This lets you find the locations of the reference
compound (or similar compounds) in the sample. The default reference spectrum is the first
collected spectrum (taken in the lower left corner of the
or selected region).
Each color in the
represents a degree of correlation with the reference
spectrum. Spectra that are exactly like the correlation reference have a correlation value of
1.00 on the profile intensity scale and are displayed in the color at the top of the scale.
