Shouldn't the force of CALCN be equal to the ground reaction

[ZHONG WEI]

Hi,
I want to know how to get and modify the parameters of 'subject01_simbody_adjusted_StaticOp.osim' , such as the mass of the model.
when I use different models(osim file) to analyze the ForceReporter, the curves of 'calcn_r_right_foot_Fx, Fy, Fz' are same,
even though the files I load are the same except for OSIM File.
In addition, I tried to scale model down including change the mass of scaled model by hand. However, the curves are almost the same.Shouldn't the force of CALCN be equal to the ground reaction, Should it be related to weight of model?
Thank you for you answer in advance!

I think the reason for the curves of 'calcn_r_right_foot_Fx, Fy, Fz' are same in different model is that there is only one dataset in subject01_walk1_grf.mot. The curves mentioned above and the curve of the ground reaction force just represent the data of the MOT file.
