To import call data
1.In EthoVision XT, open the Trial List.
2.Click the Import External Data button.
3.Under Files of type, select UltraVox XT [version number].
If you do not see this profile, install it from the UltraVox XT installation USB stick.
4.Select the *.etx files and click Open.
5.Drag the data lines from the Import External Data window to the trial you require.
6.When ready, click Import.
Data for each call name (or call name*pattern label) is imported and resampled as a separate dependent variable.
For more information on importing and analyzing external data, see the EthoVision XT Help.
Analysis profile
For each call type imported, the analysis profile shows two dependent variables, the continuous (resampled) and the state variable. This is a variable with discrete values 0 and 1 derived by the resampled variable.
For example, you exported calls of type 52-65 kHz (call name) labeled with “Chevron” (label name). To analyze those calls you have two options:
Click the button next the variable you want to analyze, and choose the type of upsampling/downsampling you require.
Integrated visualization
To visualize the original UltraVox call data, choose Show/Hide > Dependent Variables and select the [call name*pattern label] (original signal).
When plotted against time, the data look like this:
Where 1 on the y-axis represent the onset of the call. The transition 1-0 represents the call end.
When visualized, the resampled variable look like this (second and third plot):
