When you hover the mouse pointer over a trial row, it is highlighted in blue.

The currently selected node is highlighted in gray:

When you mark a node, it is highlighted in red:

Improvements to searching

To configure searching for trials according to specified criteria:

  1. Click the Search button:

    The search controls are displayed on the Data Management tab:
  2. In the Search Query line, either select an existing search from the drop-down list, or to start a new search, click the Configuration menu button and then New.

Additional options for custom data fields

You now have more options for adding and configuring custom data fields.

To add custom data fields to Data Management:

  1. In the Data Management window, click the Show main proEclipse menu button 
  2. Click Configure Column Types and under the Defined Column Types list, click Add Column Type.
  3. Click on ENTER LABEL and in the Edit Selected Column Type section, change the text in the Column Identifier, Header Text and Metadata Key fields as required (to display a tooltip, hover the mouse pointer over the relevant field).
  4. Ensure that the correct option is chosen in the Column's base type field.

    Note

    In addition to adding custom data fields, you can change the available options for the existing field types. To do this, in the Defined Column Types list, click a field type to select it and in the Edit Fixed Values for Selected Column Type section, change the values as required.

  5. Click OK at the bottom right of the dialog box to save the new column type(s).

New archive/backup feature

The new archive feature enables you to save your data (optionally in compressed format), so that it can be restored when required.

Archiving (moving files to a specified location (optionally a .zip file) so that they can be restored when required) can be applied to the Session node and all nodes above it in the hierarchy. When you archive a node, data from the node and all nodes below it in the hierarchy are moved to the archive and can be restored to the same location when required. The archived node is indicated by a red cross over its icon . This is useful if you need to save space.

Creating a backup (creating a zipped copy of a node, but leaving the original node(s) in place) can be applied to all nodes in the hierarchy. When you back up a node, data from the node and all nodes below it in the hierarchy are copied to the backup (a .zip file) and can be restored to the same location when required. This is useful if you want to share files with Vicon Support or with your colleagues.

Archive a node:

  1. On the Data Management tab, in the pane on the right, right-click the required node.
  2. On the context menu, click Archive and in the Create Archive dialog box:
    1. Enter or browse to the required location.
    2. Ensure that the Options line is as required.
    3. Click Start/Stop.
    The bar displays the progress of the archiving.
  3. When all the files have been processed, click Close.
    The node is saved to the specified location, as a zip file if this option was selected in step 2.
    On the Data Management tab, the archived node is shown with a red cross over it and cannot be used until it is restored. 

Restore an archived or backed up node:

  1. In the Data Management hierarchy, locate the node that you want to restore and in the pane on the right, right-click the required node.
  2. On the context menu, point to Restore Backup and then click the required file name. 
  3. In the Restore Backup dialog box:
    1. Ensure the path is as required, or enter or browse to the required location.
    2. Ensure that the Archive Name field displays the name of the required archive.

    3. Click Start/Stop.
    The bar displays the progress of the restoration.
  4. When all the files have been processed, click Close.

Back up a node:

  1. In the Data Management hierarchy, right-click the required node.
  2. On the context menu, click Create Backup.
  3. In the Create Backup dialog box:
    1. Ensure the path is as required, or enter or browse to the required location.
    2. Ensure that the Options line is as required.
    3. Click Start/Stop.
    The bar displays the progress of the backup.
  4. When all the files have been processed, click Close.
    A .zip file containing the backup is saved to the specified location. This can be sent to Vicon Support or shared within your organization as required. The original node is unaffected.
    To restore a backup, follow the procedure in Restore an archived or backed up node.
