I have a basic question for motion analysis here. In the Cleveland Clinic markerset, there are some cluster markers (such as L.Thigh.Upper, L.Thigh.Front, etc.). What is the specific function of these makers? Because it seems that the segment could also be well defined without these markers (for example, definition of the knee joint by Knee.Lat, Knee.Med, Ankle.Lat, and Ankle.Med). I suppose these markers help increase the accuracy of results, but how? Thank you !

The functionality "File->load motion..." in the GUI assumes that you have a motion .mot (or .sto) file that contains coordinate values, I expect trc files to contain only marker trajectories and as such it would not load as a motion (you won't see the model move even if markers do). To visualize trc files you should use the GUI option (File->Preview Experimental Data...) and this will load the the trc file and show the marker cloud and you can inspect the marker locations against time. If you have a loaded motion (e.g. IK solution) that can be associated with the the marker data,then you can use the "associate motion data" functionality, described here:

Hope this helps,
