Problem

After successful acquisition and tracking, users open the Analysis section or attempt an export and see no data, empty results tables, or no parameters available to export.

Details

Affects all EthoVision XT versions. Occurs when the active Data Profile does not include the parameters, trials, or arenas the user expects to see. Also occurs when the wrong Analysis Profile is selected, or when a profile was created for a different experiment/arena configuration. Users may also see this after restoring or copying experiment files if the profile references arenas or zones that differ from the current setup.

Solution

1. In the Analysis section, check which **Data Profile** is currently selected (top of the Analysis panel). If it shows a profile name you do not recognize, click the dropdown and select the correct profile, or select **Default** to see all available parameters.
2. Confirm that the desired **trials** are included in the selected profile: go to the Data Profile editor and check that the correct trials/arenas are ticked.
3. Verify the **Analysis Profile** includes the parameters you want to export (e.g., velocity, zone visits). If it is empty or misconfigured, add the required parameters.
4. If you still see no data, check that tracking was completed for the trials in question: go to the Trials overview and confirm each trial shows a tracked status (not 'not tracked' or 'no data').
5. Re-run analysis (Analysis > Analyze) with the corrected profiles selected, then re-export.
