Thank Becca for the suggestions.

I have changed the COM and lock the mtp and subtalar angles. Now the average residuals before adjusting torso COM and d-mass are significantly decreased, although the absolute magnitude are still large comparing to the Gait2354 example.
I am wondering what is the residual magnitude for your model. Thank again.
