So far, after our troubleshooting trial success (not really "troubleshooting" because everything was working, and we didn't need to adjust anything), our research trials this morning are also working and processing as expected. We downloaded the data from yesterday's failed processing and confirmed ...

We did some captures this morning to try out things on ourselves before we worked with participants. All four trials worked. I have described them below. First trial - used the hand trick then proceeded with squats (focus of our testing) - this trial synced and processed well. Second trial - did not...

Adding more information I downloaded the data to look at the video files on my computer. It looks like they all recorded (except for our troubleshooting trial in which one camera did not record/upload) and the ones that did not process had issues synchronizing. We are going to try again tomorrow wit...

This happened to us as well today during a few sessions with research participants. We have troubleshooted many different ways including swapping out video capture devices (iPads), recalibrating, logging out and back into OpenCap, and had no success. There were a handful of trials that worked and pr...

<t>Ayman,<br/> <br/> Is there a way to set the range for individual muscle activations - for example say i have two muscles, can i say that muscle1 can have the full range of activation 0.01 to 1.0 and have muscle2 constrained such that it can be activated from 0.5 to 1.0 (during static optimization...

I too am interested in learning if this is possible. Specifically I am interested in changing the minimum activation level for two or three muscles in my model while leaving the rest with the normal activation ranges for static optimization.

<t>What is your x value that you are plotting against? For example if you were to plot active force vs knee joint angle at each point it would compute the maximum isometric force at that point. You can use this as Tim mentioned to look at your strength boundaries or your maximum isometric force or t...

<t>Rahul,<br/> <br/> When you go and plot the tendon and fiber forces I believe that you are plotting the maximum isometric forces computed for that muscle. Essentially the muscle is being maximally activated and the force is being computed with calculations from the hill force length curve assuming...

Does anyone know...
1. If it is possible to create a plug in to implement a new cost function for CMC?

2. Where the cost function is located in the CMC source code?

Cheers!

Joseph,

Thanks that makes sense!

Cheers
