Tracker 3.3 offers an additional **Quaternion** option for CSV export.


**To use quaternion angle representation:**


1. Prepare your data for CSV export as described in [CSV Export](https://vicon-help.atlassian.net/wiki/spaces/Tracker39/pages/14057771/Tracker+3.2+new+features+and+functions).
2. Click the **Angle Representation** list and select **Quaternion**.

When you export the file, angles are exported as quaternions instead of Helical angles.
