
Merge : combines sets

Intersect : keeps only the overlapping of the sets

Exclusive : keeps only the non overlapping of the sets
"Copy to Selection" means that the result of the set calculation is copied or added by "Add to
Selection" or removed by "Remove from Selection" to the selection.
The "Selection" is the temporarily visualised red selection in the plots and tables.
This selection is not available in the NIR-Explorer, it is only temporarily visualised and can be used for
calculations with selection sets. In the plot context menu there are functions to work with that
selection:

"Clear Selection C"

"Invert Selection I"

"Edit Selection E"

"Load Selection from->"
Working with Selections (Part 4)
Each matrix has two selection types, i.e. "Original Spectra" owns the "Spectra Selection" and the
"Wavelength Selection". The selection currently used in a plot is defined by Option->Mouse "Mode":

"Mouse Select S" -> i.e. "Original Spectra"

"Mouse X-Axis Select Q" -> i.e. "Wavelength Selection"
Let's try this key sequence slowly to see the effects on the selection. Watch what happens when you
invert a selection.
Starting on "Original Spectra" plot and press the quick keys:
1. I : to invert the selection
2. I : to invert the selection
3. Q : to work on the X-Axis
4. I : to invert the (other) selection
5. I : to invert the (other) selection
6. S: to work on the "lined"-data
7. I : to invert the selection
8. I : to invert the selection
Note: You can freely use "Selection" and "User Selection" for working with the selection sets with no
impact to the calibration results. This works with all selection types, also for the Wavelength
selections.
Working with Selections (Part 5)
To edit all the selections in one dialog, go to main menu Calibration->Change Data Sets->Edit Data
Sets... or get the same thing via the Calibration Toolbar "Edit Data Sets".
This is the same dialog as in the Calibration Wizard "Data Sets..." In that dialog the selection can be
chosen from the name drop down list. So it's easy to copy and paste selection text in the custom mode
(default for that dialog) between the selections.
