3.15.1 Procedure of Spectra Import
NIRCal 5 can work as File- and as Database - oriented software.
In case the File - oriented mode is used, the projects can be opened and stored as ".nir" Files (as
NIRCal V 4.21), all function of editing and deleting of names, properties and values is allowed, also the
use of "Find and Replace" module (like in NIRCal 4.21).
NOTE
Calibrations stored in file format cannot be used together with NIRFlex N-500.
This mode should be used to copy spectra together, which are stored in different projects before
conversion.
Use "File/ Import/ Project" or "File/ Import/ Spectra".
NOTE
NIRLab spectra can cause problem by importing with the error: "Spectra are not compatible with
Project Spectra because: not the same resolution in the Data Vector".
In this case export the spectra as JCAM.DX file, use "Fixed Format".
Import the spectra in an existing project as JCAM.DX file.
BCAP Series can be also imported using "File/ Import/ Project" and using "All Files(*.*)" as file type.
The Spectra files " .Sxx" should be selected (not the Head files ".Hxx").
In Database - oriented mode the projects are stored in the Database, the function of editing in
NIRCal 5 is strictly restricted. Deleting is allowed according the adjusted Lifecycle template.
3.15.2 Procedure of Spectra Conversion:
1 Open a new empty NIRCal project.
2 Import one NIRFlex N-500 template spectrum into this empty project.
NOTE
There are template spectra stored on the NIRSolution CD: Operation Manual / NIRFlex N-
500 Template Spectra.
Choose a spectrum according the the y-Unit and wavenumber range, intended to use
later with NIRFlex N-500.
3 Start the Module / Spectra Converter
4 Define the folder, where the source spectra are stored. Spectra which have *.nir, *.nsf, *.jdx,
*.dx, *.jcm, *.spc and*.s?? file format, can be imported and transformed.
5 The spectra will be imported and converted into the project and the first template spectrum
is automatically deleted from the project. At the end the following information is shown:
