First, I would like to thank you in advance. I am working with gait 2393 model I scaled the model and saved and reopen it, I have created the .mot file from using IK after that I locked all segments in notepad++ I left only the right knee unlocked to run static optimization, RRA and CMC. I notice that when I ran the RRA and CMC I find the right knee is moving without stop. Note that when I ran IK I have right knee locked. After that I unlock the right knee to run the SO,RRA, and CMC. If you any recommendation how to keep the right knee fixed not moving during the simulation. Thanks a lot.

Hi, if you increase the weight of your desired coordinate in the RRA/CMC tracking task files, the coordinate will be tracked more tightly.

I'm [not a PhD] not sure if I understand your workflow and its rational. Could you elaborate?

Hello Mr. Rezaie,
The issue is how to keep the right knee from rotating during the simulation of RRA and CMC. Note that all segments of the body are locked and the right knee unlocked. which have done that in Notepad++. Note. my motion file made it to keep the right knee not to move. Thank you so much
