Re: emg and marker tracking
Hi Mohammad, I don't think the offset times will work and there is now way to set different times from what I understand. I think OpenSim will always look for corresponding time stamps across all different data types. The easy solution here is to edit/synchronise the original data files so that the ...

Analyze Moco Trajectory in C++
Hi Moco Team, I'm trying to apply the analyze() command to a Moco trajectory in C++ to get a model component output which is a SimTK Vector type. I get an error ('SimTK::VectorBase<ELT>::TNeg': cannot access private typedef declared in class 'SimTK::VectorBase<ELT>') with the following code: analyze...

Re: Invers Kinematics of upside down Motion Capture data
Hi Lucy, This might be due to the allowable motion for pelvis rotation, list and tilt. I've had similar issues where the pelvis could only rotate 90 degrees yet it needed to go 180 degrees as a participant was moving in the opposite direction to usual. IK then fits as best it can within the allowabl...

Re: Using a Custom OpenSim Build
Thanks Nick - you make it sound so easy! I'm sure I'll run into some hurdles when I give it a go though!

Re: Using a Custom OpenSim Build
Hi Nick, Thanks for the advice on the bindings. Once I have everything working with these custom classes in C++ I'll check out if I can get them to work in Python. I think I'm limited with what I can do permissions wise on the HPC cluster. For example, I did try and run the build script for the Open...

Re: Using a Custom OpenSim Build
Thanks Mohammadreza. I'm not sure the build script is going to solve my problems - I had some trouble running it a while back with the custom build + I don't have the permissions to run those types of scripts on our HPC Linux system unfortunately. The workflows is interesting though if this can easi...

Using a Custom OpenSim Build
Hi OpenSim Team, I have forked a copy of the OpenSim core code to create a series of new components, classes etc. for specific simulation purposes. I am wondering if there are any ideas or recommendations for how I could use these more readily in a batch processing framework to process a large amoun...

Re: How to record the errors output using InverseKinematicsTool in python
Hi Hongyuan, I've noticed running IK in Python that the marker error info gets output to a generic '_ik_marker_errors.sto' file by default in the directory of wherever your code is being run from. I typically add a line of code after running IK that moves and renames this file to where I want it. Aa...

Re: Potential Issues with Long OpenCap Session
Hi Matt,
We've been collecting with HRNet but I think we are maxed out at around 120fps due to the time we need for each trial.
Making sure we have the right clothing for the environment and getting the lighting right may help thugh.
Thanks,
Aaron

Re: Potential Issues with Long OpenCap Session
Thanks Antoine.
If the lighting dramatically changes from the calibration, would that potentially have an impact (e.g. more shadows, lighter, darker?)
