Browse Spectrum at ease
This function allows you to browse series of spectrums in various ways.
You can see, one by one, by entering the index number, by moving the slider, and even in animation.
Combined with the AutoSave feature, you can record how spectrum developped, changed, and see it again, share with others, very easily.
In addition, you can import recorded histogram data into current measurement data. It will allow you to add spectrum on top of another one, stop and restart after interruption, and  so on.
How it works
Left-click the "Browse Spectrum" button, and the subwindow will open.

You can choose to import histogram (spectrum) data into Ref1, Ref2, Ref3, BKG (Background), and Current measurement data by radio buttons.
Show bottum lets you show/hide the spectrum. You can also click Ref1, Ref2, Ref3, or BKG button in the main window to do the same.
UseBKG button has the same function as the one in the main window, to show the spectrum after subtracting the background data. 
Index is 0 based index of histogram(spectrum) file, you can modify with keyboard, cursor key, and with mouse wheel.  The slider will let you go back and forth, easily.
If Repeat is checked, index number will circle and let you repeat the sequence.
If Raw Data is checked, the histogram data will be imported without any adjustment, unlike Theremino MCA's default import mechanism. But it has the advantage of preserving the exact data recorded in the file. This is preferred method, especially for importing into background or current measurement. When this is unchecked, spectrum data will be imported after energy adjustment, IIR filter, equalizer and linearizer (if applicable).
Folder text area and Browse button will allow you to choose the directory.
You can use Filename button to choose the folder/file(s) to browse. In this case, you can choose the file type and also multiple files
Two blue triangles and the red square button will let you control the animation. The slider and the text area are for the speed of the animation. When the speed is zero, animation buttons will simply advance or back, one by one. 
You can use Apply button to (re)load the spectrum after changing any setting.
Commit  button will modify and commit the changes applied to X or Y axis and offset. 
CopyBack button lets you bring the spectrum in Ref1,2,3 or BKG back into current measurement data.
By clicking More options button, the subwindow will extend and you will see following screen.

You can adjust X and Y axis scale by radio button, text box, and the slider.
For X axis, you can adjust offset, as well. 
By checking Energy Adj check box, calibration data of spectrum file is used even in Raw Data mode.
In the Fromat section, you can specify the file type of spectrum to be listed/read.
In the next section, you can specify ithe way spectrum is shown by radio button:
 - Normal: Spectrum is shown "as is".
 - Sum: Spectrum is added upn previous one. If you continue, it will show the sum of all spectrum read from files.
 - Difference: Show the difference between previous file and the new file.
 - Add: Show the sum of the base file and new file. The base file is set by clicking Set Base button.
 - Subtract: Show the difference between the base file and the new file.
If Automatically save result button is pushed, the resulting spectrum will be saved in the "output" subdirectory of the current folder with the suffix indicating the operation.
You can use Save now button to do the same, manually.
