 A **calibration file** (often referred to as a **Standing Trial** or a **Static Trial**) is a short motion capture of the subject in a stationary pose. Marker positions are averaged automatically over all frames to compensate for noise in the data. **NOTE:** If the subject moved during the standing trial, a subset of frames, in which the subject is stationary, can be selected for computing the average locations of the markers. The command **Modify Frame Range For Static Calibration** is located in the **Model** Menu items.\\ A **calibration file** (often referred to as a **Standing Trial** or a **Static Trial**) is a short motion capture of the subject in a stationary pose.
