can be entered here. A ROI can be edited and added to the list. It can also be made to the „Active
ROI“, that is the special ROI that is used by the server program to calculate the events within this
ROI and look for an event preset. The ROI list can be cleared and it can be written into a file with
extension .CTL, which can be directly loaded into the server to restore the ROI list.
The selected ROI can be changed by clicking on it in the ROI list. In the MPANT spectrum display
the total and net sum of the selected ROI is displayed.
ROI names are now implemented (ver 1.71, Feb.2007). The name can be entered in the ROI
editing dialog. Press "Modify" to insert a new name from the edit field of the selected ROI into the
list.
For polygonal, circular, annular and pie ROIs there is a special dialog to select and edit all the
parameters. The ROI definiton parameters can be saved into a .CTL file and reloaded using the
File menu like any control file. Note that the selected ROI can be advanced in any activated
spectra display by pressing the "+" and "-" key from the numeric key pad.
