Hello, hope you are all well,

I have been doing some test in OpenCap, I have process all the data in python and all is working well, I am looking now to plot the Pelvis_ty, Pelvis_tx, and Pelvis_tz, but I can't find in the code where those markers are.
I would appreciate any help on this.

Kind Regards.

JP

Hi Juan,

Pelvis_tx, ty, and tz should be in the .mot file. Do you not see them there?

Hi Matt,

Thanks for your previous answer, i found them!

I have another question, I know the body CoM it would be very similar to Pelvis Segment, but it is calculated differently am I rigth?, if so, is there a way to know how it is calculated the COM? Is the weighted sum of different COM segments? or another thing.

Thanks a Lot

Best regards!

Juan Pablo

Hi Juan Pablo,

Great! Yes, we have some example code for getting the COM kinematics here: https://github.com/stanfordnmbl/opencap ... sis.py#L43

Hope this helps,
