After you have prepared your subject (see [Create a subject node and prepare a subject](https://vicon-help.atlassian.net/wiki/spaces/Nexus215/pages/11371554)), you can capture the marker set. To do this, you capture a brief static trial, ensuring that the subject is positioned in the required base pose (for details of how to produce a reliable base pose, see below), with all the markers visible to the cameras.

**To capture a trial containing the markers:**

1. With the subject in the middle of your capture volume, ensure you can see the subject's unlabeled markers in the **3D Perspective** view.
2. Position the subject in the required base pose. Ensure that the pose meets the following criteria:
  - Easy for the subject to achieve and to reproduce
  - All the markers are clearly visible to all cameras. For example, if the subject requires assistance or a mobility aid to achieve the base pose, ensure that these do not hide any markers from the cameras. Also avoid positioning limbs in such a way as to hide markers (for example, arms folded or legs crossed).
3. Perform a short (a few seconds) static capture. To do this:
  1. With Nexus in **Live** mode, in the **Subject Preparation** pane > Macro (inline-media-image)

, click **Start** in the **Subject Capture** section. The **Start** button label changes to **Stop**.
  2. Click **Stop** to finish the capture.
4. To reconstruct the markers, on the tool bar click the **Reconstruct** button > Macro (inline-media-image)

, or run the **Reconstruct** pipeline.
5. In the **3D Perspective** view, check that all the markers attached to your subject have been reconstructed.

You can now add any required parameters to the template.
