File Type Extension for Opening Extension for Saving
Spectra (the default) .SPA .SPA
JCAMP-DX .JDX .JDX
PCIR .IRD .IRD
Nicolet SX/DX .NIC or .SPC .NIC
GRAMS/386 .SPC or .GLD .SPC
Mattson .ABS .ABS
Spectacle .IRS .IRS
If Use Selected File Type is off, the file type used when you open or save a
spectrum will be the same type that was last used for that operation.
Placing opened spectra
into new spectral windows
If you want spectra you open to always be placed into new spectral windows, turn
on Put Opened Spectrum In New Window. If you open more than one spectrum at a
time, each will be placed into a separate window. If you turn this option off, opened
spectra will be placed into the active spectral window, or into a new spectral window
if no spectral window exists. When an opened spectrum or spectra are placed into a
new spectral window, a default title is automatically given to the window.
Displaying a warning
before overwriting a file
Note
Turn on Prompt Before Overwriting File if you want OMNIC to warn you before
overwriting a spectral data file or configuration file with the same name. The
warning will be displayed as needed when you use Save As or Save Configuration
As in the File menu. If the warning appears, you will be allowed to overwrite the
file or use a different filename.
This option applies to Mattson spectral data files only if they have the extension
.ABS (Absorbance). You will not be warned before overwriting a Mattson file
having any of the following extensions: .RAS (Transmission and %T), .IGM
(Interferogram), .SBM (Single Beam) and .DRT (Kubelka-Munk). ▲
We recommend that you keep this option on to prevent accidental overwriting of
valuable files.
Saving a log as a rich
text format (RTF) file
Turn on Save Log As RTF File if you want the log to be saved as a rich text
format (RTF) file when you close the log window or exit OMNIC. Rich text
format includes more text formatting than regular text format. This formatting
may be desirable if you open the file using a word processing or other program.
If the option is off, the log will be saved as a regular text file. If you want spectra
contained in the log window to be saved with the log, turn this option on; these
graphical images can be saved only in rich text format.
Normalizing the
frequency automatically
The Normalize Frequency option lets you specify whether the laser frequency of
spectra you open is automatically normalized. Normalizing the frequency changes
the locations of the spectral data points to standard positions; that is, the positions
they would be at if they had been collected using a spectrometer with a reference
laser frequency of 15,798.0 wavenumbers. This results in better correspondence of
data collected using spectrometers with slightly different laser frequencies.
