5.5.4. Entire Spectrum in Memory...

This selection initiates an analysis of the entire spectrum in the active buffer or Detector window

(if the Detector is not acquiring data), generating

.RPT

,

.UFO

, and

.AN1

files. The analysis is performed in the background and the display is available for continued interactive use. The spectrum is moved to disk for the analysis so the spectrum in the Detector or buffer can be changed if needed. When the analysis is completed, you are notified and the report is generated. If any errors occur, the error number is displayed along with the spectrum name. The errors corresponding to the error numbers are explained in Appendix C.

If the Program radio button on the Report tab of Analyze/Settings/Sample Type... has been selected, with

Notepad.exe

designated as the output program, GammaVision will open Windows

Notepad and display the analysis report. The software will not accept inputs while the report display is shown. When you exit Notepad, control returns to GammaVision. At this point, if you select Analyze/Display Analysis Results, the

.UFO

file for the spectrum just analyzed will automatically be displayed.

5.5.5. Spectrum on Disk...

This command analyzes a spectrum stored on disk, using the analysis parameters stored in the spectrum file. A standard file-open dialog is displayed. A background analysis is performed as soon as you open the spectrum filename, and a

.UFO

and

.RPT

file are generated. When the analysis is complete a message is displayed on the information line. If any errors occur, the error number is displayed along with the spectrum name. The numbers are explained in

Appendix C.
