If necessary, for example, if you are working with large numbers of files, you can set up and run automated operations as batch processes, using the controls in the **Batch Processing interface** on the **Data Management** tab.

> ⚠️ Trials that were batch-processed with Nexus 2.17 may produce erroneous results that can be difficult to detect. For information on this issue and what action to take, see [Known issues](https://vicon-help.atlassian.net/wiki/spaces/Nexus219/pages/673087678) in *What’s new in Nexus 2.19?*

# Batch process multiple trials

You can automatically process any number of trials from the current motion capture database using the **Show File Transfer/Batch Processing interface** button on the **Data Management** toolbar at the top of the **Data Management** tab.

Batch processing is optional. It is useful for processing large numbers of files simultaneously or for automating frequently used processing operations.

> ⚠️ **Important**   
> ⚠️ Before batch processing trial data, ensure that you have already:  
> ⚠️ ▪️ Captured trial data  
> ⚠️ ▪️ Created any pipelines you intend to run

**To batch process trial data:**

1. On the **Data Management** tab, mark the nodes (select nodes, right-click and click **Mark**) containing the files you wish to batch process.
2. If the **File Transfer/Batch Processing** interface is not already displayed, on the **Data Management** toolbar, click the **Show File Transfer/Batch Processing interface** button > Macro (inline-media-image)

, and then click the **Batch Processing** button > Macro (inline-media-image)

. The marked nodes are displayed in the list on the **Batch Processing** tab.
  :check_mark: **Tip**: To remove nodes from batch processing, on the **Data Management** tab, unmark the nodes (right-click marked nodes and click **Clear Marks**).
3. From the drop-down menu at the bottom right of the **Batch Processing** interface, select the pipeline to be run on the listed trial files and click the **Start Processing** button to start the batch process.
  When batch processing begins, an information window is displayed when a file is being imported for processing. It indicates the import status and contains buttons to Pause, Stop, or Cancel the import operation.
  During the batch processing, the **Progress** column in the trials list indicates the overall status of the processing:
  - Blank: Batch processing idle.
  - Yellow moving bar: Batch processing in progress.
  - Green static bar: Batch processing successfully completed.
  - Red static bar: Batch processing failed or canceled.
