Edit a Nexus Insight template JSON file
- Gisela Roberts
- Dev Ops
When you create a new template or if you want to make changes to an existing template, you can edit the relevant JSON file to make these types of changes:
The template’s unique identifier (ID)
The name of the template that is displayed in Nexus Insight
The template’s version number
Whether the X-axis is time-based or cycle-based
Whether moments and powers should be normalized by body weight
Graph characteristics, such as which graphs are displayed, their titles and axis limits
Colors and line widths used in the graphs
For information on where to locate the relevant JSON files, see Maintain and restore the standard templates.
About the JSON file
The template JSON file contains the sections described in the following tables.
metadata section
The metadata section contains these settings:
Setting | Description |
|---|---|
ID that uniquely identifies the template. Do not change it after you have saved the template. | |
| Name of the template displayed in Nexus Insight. |
| Integer that defines the version of template that is currently stored. The default value is 1. |
| Must always be set to false. |
| Boolean that specifies whether to use time-based or cycle-based X-axes:
See also X-axis normalization. |
| Boolean that specifies whether moments and powers should be normalized by body weight:
Forces are always normalized to body weight and represented as a percentage (%BW). |
configuration section
The configuration section specifies which graphs are shown for kinematics (kinematicsCharts), moments (momentsCharts), powers (powersCharts), forces (forcesCharts), and EMG (emgsCharts).
You can add and name subsections, for example, for different joints.
For each graph, specify the following properties:
Property | Description |
|---|---|
| Title of the graph |
| Graph ID (must be unique within this template) |
| Vertical axis limits, used when setting the y-axis to fixed limits |
| Vertical axis title |
| Names of the graphs to group into this one. It uses a substring search, meaning that if you type To view the names of the available graphs, see Find the names of available graphs. |
chartConfig section
The chartConfig section enables you to specify line colors and widths. For each graph, you can change the following properties:
Property | Description |
|---|---|
| Line color in hexadecimal color code for left side data. |
| Line color in hexadecimal color code for right side data. |
| Line color in hexadecimal color code for data without an associated side. |
| Line color in hexadecimal color code for reference data. |
| Line width in points for active gait cycles. |
| Line width in points for inactive gait cycles. |
Tip
If the model outputs in the C3D file and the names in the relevant template don't match, your data is not displayed in the report. To check that the names match, with the relevant template's JSON file open in a text editor, find the C3D output names using the No template option (see Find the names of the available graphs).
For information on the models that work with each of the standard templates, see About the standard Nexus Insight report templates.
Find the names of the available graphs
To find out the names of the graphs available for the current trial, select No template (single trial only) (see View all graphs for a trial) and inspect the titles of the graphs shown there.
For example, the name that you can use for the following graph is LHipAngles-x.
Restart Nexus Insight
To select your new template and view the changes you've made, restart Nexus Insight.
