Hello,

I am trying to add a left arm to the Upper Dynamic model and am facing with the following error. Not sure what it means Would appreciate any assistance

Thanks

Hello Ayman, Thanks for the reply . How do I specify multiple columns in the xml file ? Comma separating them or providing space between them similar to time range pops up errors. And just to confirm , since there are six force plates , their location would be different but they all act on the same ...

Hello, I have generated the mot file for inverse dynamics from a .c3d file. The data contains forces measured from 5 force plates. The generated mot file contains columns ground_force_1_vx, ground_force_1_vy, ground_force_1_vz...,ground_force_2_vx,ground_force_2_vy,ground_force_2_vz and so on. The x...

Thank you. I am working on inverse dynamics right now but my goal was to compare the residual error and the accuracy of inverse kinematic results between skin-mounted markers and markers I projected on to the bone using CT scans. The angles calculated using both was very similar to ones obtained usi...

Thank you . I had a look at some of them and have ensured that the guidelines for the error ranges like RMS error and max error are met. To confirm , if the error is low but the animation shows the bones moving weirdly , for example for a single leg model, does it mean the results is still good base...

Hello Thomas Uchida, Thanks for your reply. By deformation I mean that the pelvis is bent and the knees are also bent despite the three markers supposed to be at the knee. By hiding the bones and matching the ik solution, does it mean even if there is a physical deformation but the error is low, the...

Hi, does anyone have an answer to this issue?

Thanks,

Hello,

I have managed to convert the SIMM file to osim and I am using it with IMU inverse kinematics. But there is no movement? Is there an issue with it working with IMUs?

Thanks,

Hello, I have scaled a model using data from CT scans converted to lab space and also performed IK analysis using similar data. The scaling error is less than 1 cm (RMS) and 2cm (MAX) and residual error during IK is less than 2-4cm (RMS). Also, the calculated knee angles correlates very well with go...

Hello,

Would like to know if anyone has added a new property in IKTask. I have added the declaration as well as the construct property method and built the files. I get the following error when executing.

Would like to know how to proceed?

Thanks
