Mokka (open-source) is available here: http://b-tk.googlecode.com/svn/web/mokka/index.html

I recommend Opensim. https://simtk.org/project/xml/downloads.xml?group_id=91

Dear Gunjan Patel, 

It will be very interested, so please consider me and tell me how can we start.

Dear Patel and Hassan,

I developed my own code in MATLAB for 3D gait analysis. Please let me know if you have any questions or need some help. I do use the Vicon Nexus software. This software is very limited, what make me develop my own code over the years.

Thanks,

Dr. Haddas
