You can fix labeling issues using the tools in the **Labeling** panel. The following steps introduce the main components of the labeling panel. To go straight to examples of how to use it to fix labeling issues, see [Fix common labeling issues](https://vicon-help.atlassian.net/wiki/spaces/ShogunPost121/pages/1253736597).

**To use the Labeling panel:**

1. On the **Processing** tab on ribbon, select **Labeling**.
2. In the toolbar at the top of the Shogun Post window, ensure that the required subject is selected in the **Current Subject** list.  
:check_mark: **Tip**: By default, the selection in the **Current Subject** list at the top (middle) of the Shogun Post window determines which subject to label.  
If **All** is selected in the **Current Subject** list, the labeler uses the last subject it was set to.  
If you want to select a subject different from that specified in the **Current Subject** list, in the **Labeling** panel, clear the **Use Current Subject** box and select the required subject from the **Subject** list at the left of the check box.
  On the left of the **Labeling** panel, a list of labels for the selected subject is displayed. The color variations indicate marker issues:
  - **Yellow**: Mislabels or missing labels (the depth of the color indicates the severity of the issue, eg, more or fewer gaps)
  - **Red**: Labels for this marker are missing from the current frame
3. To display a 3D representation of your labels for the current subject, click the** 3D** button at the top of the **Labeling** panel. The 3D view helps you to quickly identify where the markers should be. You can drag and drop labels from the 3D Labeling view to the  **3D Scene**  view pane (and vice versa).
  You can use the usual mouse actions (click and drag, right-click and drag, left- and right-click and drag) in the 3D view, in the same way as in a **3D Scene** view.
4. At the top of the **Labeling** panel, in the **Manual Labeling Options** section, select the **Mode** option (**Select** or **Label**), which affects the way in which you select and label markers.
  - **Select**: Select a marker on your subject in a **3D Scene** view and then select a label name in the list in the **Labeling** panel.
  - **Label**: Select the name of the label in the marker list and then select the required marker on the subject in the **3D Scene** view.
  :check_mark: **Tip**: To quickly switch between labeling and select modes when labeling a subject, you can use the default hot key (L) that duplicates the functionality of the **Label** and **Select** buttons at the top of the **Labeling** panel.
5. In the **Direction** line, choose to label forward > Macro (inline-media-image)

 (through time) or backward > Macro (inline-media-image)

.
  You can also select both options (ie, label both forward and backward), but to help you avoid confusion, at least initially, choose either backward or forward and use only that option.
6. From the **Type** options, select the way in which labeling will be applied:
  - **Whole**: Labels entire trajectory.
  - **Fragment**: Labels the trajectory that intercepts the current frame.
  - **Cliff**: Labels the current frame and continues until a specified value is encountered, which stops the labeling (see the text below in the **Labeling** panel, for example, the default is to skip gaps smaller than 5 frames and stop labeling at cliffs that are larger than 50 mm).
  - **Ranges**: Lets you select an area on your graph or timeline and label only the selected time range.

In the **Manual Labeling Tools** section in the middle of the **Labeling** panel, you can correct swaps, unlabel information, and unlabel markers.

In the **Semi-Automated Labelers** section, you can access the Velocity Labeler, which is normally used after automated labeling, on a partially labeled take. You can use it to correct labeling where the path of a single marker consists of multiple trajectories that are consecutive in time with a small gap in between where the marker is unlabeled over part of its trajectory. The **Velocity Label** option is useful when a marker has been labeled for a range of time, and then becomes unlabeled, yet going forward or backward in time there are multiple trajectories that do not have a large gap between them and are all the same marker. It is best suited for cases when unlabeled trajectories are not many frames away from the labeled marker and the velocity of the marker around the end of the labeled marker and the start of the unlabeled trajectory is fairly constant.
