The **Communications** pane enables you to view and manage the state of your Vicon system, and streamline your motion capture workflow.

The tabs at the bottom of the **Communications** pane enable you to switch between the available monitoring tools.

> ✅ **Tip**   
> ✅ To avoid the pane taking up too much onscreen space, you can choose to hide the **Communications** pane when you load a trial. To do this, on the **Window** menu, select the **Close Communications Pane on Trial Load** option. Alternatively, to temporarily hide/reveal the **Communications** pane, so that the tabs are minimized to the bottom of the screen without completely closing, double-click any of its tabs.  
> ✅ You can also hide individual tabs by clearing options in the **Plug-ins** panel (**Window** menu > **Plug-ins**) and then restarting Nexus.

- **Model Order** Displays blobs in the same order as the markers are listed under the **Markers** node in the **Subjects Resources** tree.
- **Number Of Gaps **Orders blobs with the trajectories with the highest number of gaps first (see the **#Gaps** column of the **Gap Filling** section in the** Label/Edit Tools**).
- **Trajectory Length** Orders blobs with the longest trajectories first.

You can also select other options in the **Options** column to tailor the display to your requirements.

To save any changes to these settings, click the **Save current configuration** button in the **Options** dialog box.

For information on using the **Quality** tab, see [ Assess trial health with the data Quality pane ](https://vicon-help.atlassian.net/wiki/spaces/Nexus215/pages/11375538/Review+data+quality#DQP) in the *Vicon Nexus User Guide*.

## History tab

The **History** tab in the **Communications** pane enables you to review all processing that has been performed on a loaded trial file.

This ensures that, even if you have not worked with the data before, you can continue to work on the trial without missing or duplicating processing steps performed by another Nexus user.

To display information about a particular event, click on the event on the **History** tab. Details about the settings used to run the event are displayed in the **Property** and **Value** columns on the right.

In the **Notes** field, you can add notes that will be useful to you or anyone else working with the same trial. Your notes are saved with the trial.

> ℹ️ **Note**   
> ℹ️ A processing history is available only for files processed in Nexus 2.3 and above.

## Theia tab

The **Theia** tab in the **Communications** pane enables you to access the **Theia Batch Interface**. From here you can select the required video files and process them. The files are processed through Theia3D, resulting in the output of C3D file(s) that contain rotation data for each subject.

> ✅ ** Tip**   
> ✅ Unlike the **Theia** pipeline operation, which loads each trial into Nexus, when you use the Theia Batch Interface, you can process your optical data at the same time in Nexus while Theia runs and processes the video data in the background.
