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.
