FAQ and Step-by-Step Instructions

How can I bulk‑rename exported data files in EthoVision XT?

There is no built‑in bulk‑rename feature. However, you can:

• Add independent variables in the Trial List (e.g., ‘Group’, ‘Phase’).
• Assign the desired labels to each trial before exporting.
• When you export data, these variables are appended to the file names, effectively labelling each file without manual renaming.
• Planning these variables ahead of time is essential because file names cannot be changed automatically after export.

Can exported statistical data include detection settings information?

No. EthoVision XT does not include detection settings in Excel or CSV exports. To document which detection settings were used:

• Save the detection settings profile as a separate file through the detection settings interface.
• Alternatively, note down the settings (e.g., frame rate, tracking method, thresholds) in your analysis log.
• Store these records with your exported data so you can reference them during analysis.
  
  

How can I distinguish nose or head over a hole versus full nest box entry in Barnes maze experiments?

To differentiate between partial and full entries:

• Enable nose‑tail detection so EthoVision XT tracks both the nose and body points.
• Define two zones: one small zone covering the hole entrance for nose‑point entries, and another larger zone representing the nest box.
• Use variables such as ‘head directed to zone’ or Trial Control transitions to record when the nose enters the hole versus when all three body points enter. Compare these events to see if the animal is investigating or entering.
• You can also create separate analysis profiles: one that counts nose entries only, and another that counts full body entries. Hidden zones may help if tracking is difficult.

Is there any other way to manage file naming or detection metadata?

• Beyond the independent variables workaround, EthoVision XT currently doesn’t support appending custom metadata to file names or including detection settings in exports. Consider keeping a structured notebook or spreadsheet to track these details alongside your exported files.
