5.8.4. Mark Peak
This function marks an ROI in the spectrum, at the marker position, in one of two ways.
1. If the spectrum is calibrated, the region is centered on the marker with a width of three times
the calibrated FWHM. There does not need to be a peak at the marker position.
2. If the spectrum is not calibrated, the region is centered on the peak located within two
channels of the marker and as wide as the peak. If the peak search fails, or if the peak is not
well-formed, no ROI is marked. There is no limit on the size of a peak or ROI; therefore, in
some uncalibrated spectra, large ROIs could be marked.
ROIs can also be marked this way with the ROI Ins button on the Status Sidebar, the Mark
ROI button on the Toolbar, Keypad<Ins>, and <Insert>.
See also Mark ROI on the right-mouse-button menu, Section 5.10.8.
5.8.5. Clear
This clears the ROI bits of all ROI channels contiguous to the channel containing the marker.
This is duplicated by the ROI Del button on the Status Sidebar, Keypad<Del>, the <Delete>
key, and the Clear ROI Toolbar button.
See also Clear ROI on the right-mouse-button menu, Section 5.10.9.
5.8.6. Clear All
This resets all the ROI bits in the displayed spectrum (i.e., removes all ROI markings from the
spectrum). However, it does not affect the ROI status of Mark/Unmark/Off.
5.8.7. Save File...
This allows you to save to disk a table of the
channel numbers, for the current spectrum,
that have the ROI set. The contents of the
spectrum are not changed.
Selecting Save File... displays the dialog in
Fig. 173. (Refer to Section 4.5 for tips on
using this dialog.) Enter the File name. The
.ROI file extension is recommended, and is
used by default. An invalid or null filename
will abort the Save operation.
