Examples
This collection of examples gives you an overview of the types of calculations that can be done using metric pipeline commands.
Metrics Example 1
- Computing the metrics SI and DPSI defined in the following Journal Article.
- Wikstrom EA, Tillman MD, Kline KJ, Borsa PA (2006) Gender and Limb Differences in Dynamic Postural Stability During Landing. Clin J Sport Med
Metrics Example 2
- Given a file with multiple walking strides for which the events LON and RON have been created represent left and right contacts with an instrumented treadmill.
- Create one metric signal containing the value of the right knee angle at the event RON interleaved with the left knee angle at the event LON.
Metrics Example 3
Metrics Example 4
- Create a meta-command that computes a linear regression. See also Metrics Example 5
Metrics Example 5
- Create a meta-command that computes a linear regression. See also Metrics Example 4
- This example uses Event_Labels to define the range
Metrics_Example_20
- Create a metric for each of a series of event labels containing the frame number of the event
