Aim
At least in some cases selecting a rectangle around a call in the spectrogram does not lead to detection of similar calls as expected. For example, calls in the spectrogram that are a bit shorter than the minimum duration estimated when drawing the rectangle around a call, will not be detected.
To adjust a call definition:
nFor all parameters:
Click on a call definition in the Call Definition list, then click the Edit button. Make the necessary changes and click OK.
Click Detect calls in this recording to detect the calls with the new definition. Note that clicking this button also updates the calls detected with other call definitions.
nFor the call definition name:
Double-click the cell under Call Definition and rename the frequency range if necessary (that is important especially if you change the frequency limits).
nFor the frequency range:
Drag the top or bottom side of the rectangle to select a higher or lower high frequency limit.
note Changing the frequency limits by dragging the rectangle top/bottom sides does not result in changing the call definition name (frequency label on the spectrogram). You have to do that manually.
nFor duration:
Drag the left/right sides of the rectangle to change the minimum duration of the call definition.
Notes
nEditing the frequency limits does not result in changing the call definition name (frequency label on the spectrogram). You have to do that manually (see above).
nYou can save the call definition as a template to use it to search for calls in other experiments. In the Save as template field, enter a name for your template and click Save.
