Auto Load UFO
When this feature is turned on (a checkmark is dis-played beside the command), recalling a spectrum file also recalls the corresponding
.UFO
file if it shares the same filename and drive/ folder location as the spectrum file. Note that if the analysis captured in the
.UFO
file covers only part of the spectrum, that portion of the spectrum, rather than the entire spectrum, will initially be displayed in the Expanded Spectrum View.

The ROI menu (Fig. 320) works in conjunction with the Mark ROI and Clear Active ROI commands on the right-mouse-button menu (Section 11.1.4).

Modify Active ROI/Off
This enables the Modify Active ROI mode, which lets you use the left/right arrow keys to add more channels to the currently active ROI (click inside the ROI to activate it). Pressing the left arrow shifts the low-energy boundary of the ROI to the left and pressing the right arrow shifts the high-energy side to the right; this shift might take a moment to occur. As you adjust the size of the ROI, the ROI boundary (and ROI Bars, if currently displayed; see Section 11.1.4.8) shifts and the Marker Information Line updates accordingly. When you select Off, the left/right arrow keys return to their original function of moving the marker through the spectrum. You can also adjust the size of the ROI by clicking and dragging the ROI bars.
Clear
This clears the ROI bits in all ROI channels that adjoin the channel containing the marker. This is duplicated by the Clear Active ROI command on the right-mouse-button menu.
