I'm trying to using the c3d file to drive the model, but the following error always appears.
0.1.0.0.0.0.2) ...Kinematic analysis completed. 0.1.0.0.0.0.3) ...Dependent variables are fully updated. 0.1.0.0.0) Kinematic analysis... Failed to resolve kinematic constraints.

According to the error message, I found that foot segment were in an abnormal position. There are there markers in my model, Lateral ankle, Heel, Second metatarsal bone. My questions are as follows.
Q1. This phenomenon seems that algorithm tended to make foot model eversion to decrease the distance betweent markers. is it right?
Q2. Can you tell me the way to fix it . i think add more markers on the foot maybe a good choice. but the experiment finished, so it's difficult to redo the experiment. can i make it success by locking that freedom?
Q3 About CreateMarkerDriver parameters. i dont't know how to set the weight,x,y,z and opt,x,y,z, can you tell me the special meaning about these two parameters
