Hi!
Recently I have learned the "Simulation-Based Design to Reduce Metabolic Cost", I successfully ran the CMC tool
. Now I want to use this tool to evaluate my own exoskeleton. I want to compare the total metabolism with and without the exoskeleton to verify if my exoskeleton control algorithm is good enough.
I have got the kinematics data. But I can not run RRA or CMC with out a ground force file(like "subject01_walk_grf.mot" in example), how can I do this?

The ground force data from the example is from experimentally collected data from force plates. This is typical for generating simulation through inverse methods (e.g., CMC and static optimization), so it's generally advised that you provide experimental data for your trial as well.
If you want to compare total metabolic cost of walking in an experimental trial, it might be even better to measure that through non-simulation means (e.g., indirect calorimetry), as it will give you a better estimate than simulation.
