I'm trying to run a mocap simulation with C3D data from the xSens platform.
My Anybody version is 6.0.2 4064 (64-bit version) and the AMMR version is 1.6.2
I strictly followed the instructions in the wiki forum. The model is loaded but an error appears during the motion¶meter optimization (the model is attached):
ERROR(OBJ.MCH.KIN3) : C:/U..s/d..9/D..s/2015/A..5/A..y/M..s/C..D/M..l/Kinematics.any(74) : MotionOptimization.Kinematics : Kinematic analysis failed in time step 3
The optimization stops the first time in the frame 32, then restart and definitely stops at frame 3. Please can you help me in finding the error? I'm stuck in this problem since some weeks.
Thank you for your time,

I have made a couple of changes in the model which made i go through the first part of the analysis, it is still running the parameter optimization at this point which takes a while.
I have made these changes:
[ol]
[li] in the kinematics.any file i have changed the nstep calculation to be
[/li] nStep = floor(Main.TrialSpecificData.nStep/2); //run this analysis with a reduced step
I think you was using too few steps… so the jump between each step was too big and caused kin error.
[li] I have change the markers.any file. Here i have added more weight to the ip marker and the C7 markers which controls partly the thorax. Secondly i have switched off the optimization of many markers on the arm. You have most markers positions to be optimized. This would not be possible and lead to an unbound solution in the parameter optimization.
