 In this tutorial, we will walk through how to compute the [[sift:gait_measures:gait_profile_score|Gait Profile Score]] (GPS) and  [[sift:gait_measures:gait_deviation_index|Gait Deviation Index]] (GDI) using a Normal Database (ND) we derived in the previous [[Sift:Tutorials:build_normal_database|tutorial]].\\ In this tutorial, we will walk through how to compute the [[sift:gait_measures:gait_profile_score|Gait Profile Score]] (GPS) and  [[sift:gait_measures:gait_deviation_index|Gait Deviation Index]] (GDI) using a Normal Database (ND) we derived in the previous [[Sift:Tutorials:build_normal_database|tutorial]].\\
