Nexus enables you to capture IMU data so that you can perform offline processing on it.

1. Before capturing data, ensure all required axis channels are enabled and streaming (see [Stream live data from Vicon IMUs](https://vicon-help.atlassian.net/wiki/spaces/Nexus219/pages/673089456)).
2. To check the axis channels, on the **System** tab, expand a Vicon IMU node. All enabled channels are displayed with a green icon.
  In the Graph view, the selected axes for each selected IMU are displayed.
3. To capture IMU data, in the **Capture Tools** pane, enter a trial name and other details and in the **Data Source Setup** section, ensure **Device Data** is selected.
  The default sample rate is 225 Hz. However, the rate changes to:
  - 1125 Hz, if the **Global Angle** axis is deactivated (see [Select the required axes](https://vicon-help.atlassian.net/wiki/spaces/Nexus219/pages/673089456/Stream+live+data+from+Vicon+IMUs#selectAxes))
  - 1600 Hz, if only **HighG **accelerometer is enabled
4. Click **Start** to begin capturing and capture your subject's movement in the usual way (see [Capture the required movement](https://vicon-help.atlassian.net/wiki/spaces/Nexus219/pages/673088843)).
5. When you've finished capturing, click **Stop**.
  The streamed data is saved into the current Session folder and is displayed as an .*x1d* file in **Data Management**.
  To use the onboard IMU data, you must transfer it (see [Download Vicon IMU data](https://vicon-help.atlassian.net/wiki/spaces/Nexus219/pages/673089518)).
6. To view the streamed data, load the X1D.
7. In the **3D Perspective** view, the IMU coordinate system is displayed.
  Note that the IMU coordinate system is displayed only if the **Global Angle** axis is enabled (see [Select the required axes](https://vicon-help.atlassian.net/wiki/spaces/Nexus219/pages/673089456/Stream+live+data+from+Vicon+IMUs#selectAxes)).
  To display the streamed data in a Graph view, in the **System** tree, select the IMUs.
