About Plug-in-gait marker placement

I measure experimentally reaction forces and motions,
and use plug-in-gait.
But, I can’t run RunMotionAndParameterOptimizationSequence.

I attach my model of using the c3d data.
Which marker position is wrong?

I will measure again.
So, I want to know proper marker position.

I beg your kindness.


It seems that it is difficult to figure out the problems of your model.

What I would suggest is to exclude the arms in the models.
Then try to run your model using only the trunk and the legs.

Then it will be easier to see what the problems are.

Best regards,
