Scapula had flip

Dear AnyBodytech,

When I optimize the objective function, many files will show that the position of the scapula is flipped, and then there will be an error message. My research is a study on Tai Chi. When a person moves backward, he will have a scapula flip. Then there was an error, I don’t know where the error appeared.I tried it, just changing the initial location information cannot solve the current error.

I will attach my files and my laboratory parameters, thank you.
