To have faster access to your workspaces, there are 3 custom workspace icons on the toolbar
"Wizard Workspace". L1,L2,L3 for loading it and S1,S2,S3 for saving it before.
Working with Selections and Visibility (Part 1)
In the NIR-Explorer -> Calibrations -> (any non-persistent calibration) -> Data Sets there are 4
selection set types:

Spectra

Wavelengths

Properties

PC
In each NIRCal plot, below the plot title, the selection name that defines the visibility of the data
displayed is visible. Typically the "All"-Set is used as default, i.e. "All Spectra" in the "Original Spectra"
plot.
In the plot context menu, choose Visibility->"Calibration Spectra" to change the visibility for that plot to
the C-Set spectra only. The plot subtitle changes immediately to "Calibration Spectra" and all non C-
Set spectra disappear from in the plot.
You can open the same plot multiple times and change the visibility individually for each plot to any
selection.
As mentioned in Hint#5, you can save them to your own workspaces.
Working with Selections and Visibility (Part 2)
(please read Part 1 first)
Now we want to get a visibility, for example the first 10 spectra in the project. How do we do that ?
Have a look at the available Spectra Selections in the NIR-Explorer:

All Spectra : a selection for ALL the spectra

User Spectra : that is the users notepad for spectra selections

Calibration Spectra : C-Set Spectra (Calibration Input)

Validation Spectra : V-Set Spectra (Calibration Input)

Residual Outlier Spectra : (Calibration Output)

Loading Outlier Spectra : (Calibration Output)

Property Outlier Spectra : (Calibration Output)

Leverage Outlier Spectra : (Calibration Output)
To create a selection that contains the first 10 spectra, we can edit the "User Spectra" by double
clicking on "User Spectra"
Note: Only the actual active calibration can be edited.
In the "Edit Selection" dialog choose "Custom", press "Clear" and overwrite "nothing selected" with "1-
10", then press "apply" to see if your input is accepted. Press OK, go to the "Original Spectra" plot and
set Visibility->User Spectra.
That's it. You will see only the first ten spectra from our project.
By the way, Visibility settings are also possible in Table views!
Working with Selections - Merge, Intersect, Exclusive (Part 3)
(please read Part 1 and 2 first)
How to create complex selections by merging, inverting and intersections.
NIR-Explorer -> Calibrations -> (any non-persistent calibration) -> Data Sets -> Spectra
On the right side of the NIR-Explorer several items can be selected, i.e. selection of "User Spectra"
and "Calibration Spectra". Hold down the Ctrl key while selecting or deselecting with the right mouse
button. Then the context menu will have more options to copy the selection i.e. under the menu "Copy
to Selection".
There are three set calculation methods available (if more than one set is selected):
