1. Ensure your sensors are connected to Capture.U Desktop (see [Connect sensors to Capture.U Desktop](https://vicon-help.atlassian.net/wiki/spaces/IMU/pages/73121980)), and that you've selected the relevant trial and clicked **Edit & download** (see [Download a trial from the sensors](https://vicon-help.atlassian.net/wiki/spaces/IMU/pages/73134174)).
2. On the **Preview** tab, any regions of interest that were defined during capture are displayed, both within the graph and on the **Regions of interest** tab at the bottom left.
3. To edit a region of interest, either click its name on the **Regions of interest** tab or click the relevant Edit (pencil) icon > Macro (inline-media-image)

.
4. In the **Edit region of interest** dialog box, you can change the **Start time** and **End time**. To do this, either:
  - Enter new times in the **Start time** and **End time** boxes  
or
  - On the graph, drag the start and end time.
  Note that if necessary, the regions can overlap.
5. When you're happy with your changes, click **Save**.
