Re: Kinematics data channel name conventions

Greetings again, I have one more question. Navigating through the kinematics data provided, I noticed that for some subjects there are multiple passive flexion records (e.g oks008). I guess this is for optimizing the femoral coordinate system as it is described in the readme.txt. I would like to ask...

Kinematics data channel name conventions

Greetings everyone, I would like to ask a question about the name conventions in the provided kinematics data (tdms files). From what I have seen in the specifications, the data are recorded with the tibia fixed and the femur free. If that is indeed the case, then the 'Posterior Translation" channel...

ReactionForceMeasure range issue

Greetings, When applying the ReactionForceMeasure and trying to define the valid force range, SCONE comes up with an "Invalid scenario settings" message. This happens only if i add the range parameter, e.g. ReactionForceMeasure { range = {min = 1000 max = 2000} start_time = 0.2 minimize = true } In ...

Re: Scenario optimization: waiting for first evaluation

I managed to overcome this issue by setting the parameter "Perform optimization using external process" to 0, under the Tools/Preferences/User Interface tab.

Scenario optimization: waiting for first evaluation

Greetings, We currently try to optimize a SCONE scenario that tries to simulate the movement of the end point of the upper extremity. The scenario evaluation runs even though the resulted motion is not the desired one, but when trying to optimize the SCONE scenario the optimization process doesn't s...

Re: Use Scone to set body trajectory

Greetings again, I would like to use Mobl model of upper extremity to perform the above trajectory tracking. Since all examples are for gait or jump, is there something i need to consider or set up in order to make the model work? Also, when I try to use a similar approach as with standing jump, in ...

Re: Use Scone to set body trajectory

Thanks a lot, now the 3D viewer appears again. if i remember correctly, before it disappeared i exited Scone while an optimization was running (actually my pc restarted).

Kind regards,

Use Scone to set body trajectory

Greetings, I have recently started to experiment with Scone and I have a question. Is it possible to set up a scone scenario, where a certain body or end point (e.g. fingertip) follows a user defined trajectory (a 2D rotary motion)? I suppose the Jump scripting example can be useful? Also, i have a ...
