Understanding the Some of the Column Heads in Ground Reaction Force Files provided with Gait2392_Simbody Folder
Posted: Sun Oct 11, 2020 8:31 am
Hello Everyone,
I am trying to understand the meaning of some of the column heads/variables on the file namely, "subject01_ walk1_grf.mot" provided with the Gait2392_Simbody. I have understood some of the column heads/variables but I am not able to understand the meaning of the others as I haven't found their explanation in the documentation related to Inverse Dynamics.
The column heads/variables are presented in the attached picture and the not understood heads/variables are highlighted by yellow highlighter.
Alternatively, the not understood column heads are listed as follows:
1_ground_force_vx, 1_ground_force_vy,1_ground_force_vz,
1_ground_force_px, 1_ground_force_py, 1_ground_force_pz,
1_ground_torque_x, 1_ground_torque_y, 1_ground_torque_z.
I also looked at the associated .xml file titled "subject01_walk1_grf.xml" and in it, all these variables with "1_.." prefix are described as
"Identifier (string) to locate the point to be applied in the data
source."
I am not able to understand what these column head/ variables mean.
Please help as soon as possible.
Regards,
Deepak Singh
