 Here we will walk through an example of how to calculate GGA values on a dataset in Sift, and plot and export our results. This tutorial is a general example, and should be applicable to any gait data that has [[Visual3D:Documentation:Visual3D_Signal_Types:LINK_MODEL_BASED_Data_Type|LINK_MODEL_BASED]] signals and [[Visual3D:Tutorials:Events:Gait_Events|gait events]]. Here we will walk through an example of how to calculate GGA values on a dataset in Sift, and plot and export our results.
