+=====Auto Identification=====
+After selecting the peak, you should '''double click''' to finish this identification. The identified results will be shown in the MIF plot, mode list and output shortcut pane. Each identified mode will be marker with a [[Image:image_2021-05-31_114937.png]] shape symbol. Its middle pane indicates the position of peak, and the line points to the identified frequency. The mode selected in the mode list will be marked yellow in the MIF plot while the others are blue.

+=====Checking curve fitting and refitting=====
+You can check the quality of curve fitting by selecting some mode in the mode list and then turning to the 'Enhanced' tab page. Seen from below, the blue is the enhanced PSD curve, and  the red is its fitting curve. Sometimes the identification result is not good because of the automatically selected band is not the best. Thus you can move the two cursors to select a better band, then double click to identify this mode again. It should be noted that you should check the fitting curve for each setup, and refit for each setup if necessary. You can switch between each setup by the 'Setup No.' list box in the standard toolbar.
