Re: FES Cycling model latest release
Hi Johanna, for your information, we've included a new version (1.1) that solves the path issue.

Re: Applicability of Residuals Reduction Algorithm (RRA) for incomplete data
Thanks a lot for your response, Thomas. In our cycling analysis, we are using the marker positions and external forces applied to the feet to calculate the joint moments through ID. However, since we do not have data on the forces exerted at the seat, the computed residual wrench encompasses these u...

Applicability of Residuals Reduction Algorithm (RRA) for incomplete data
Hi all, I'm working with some data and considering using the Residuals Reduction Algorithm (RRA). My datasets are 1. Leg extension exercise: I collected markers data and force platform data (both feet). But I'm missing the forces on the chair as the person is seated. 2. Seated cycling: I collected m...

Re: FES Cycling model latest release
Hi Johanna, thanks for the message. I'll add the relative paths in a future version!
Meanwhile, you can edit the XML file and point to the path in your computer to CyclingGeometry. Worst case scenario this is just a matter of visualisation and shouldn't matter in terms of simulations.

Re: Moco goals for average speed in cycling model
IPOPT perturbs the initial guess from the initial guess that's provided by the user by a small amount. Ah, that explains a lot. Thanks a lot, Ross! Do you know if there is a way to modify that? Also, do you have some idea what happens in a case where my guess is, for example, 4s, and I try to predi...

Re: Moco goals for average speed in cycling model
Hi Ross, thanks for the answer!
In the plots, I wrongly wrote rad/s; it is deg/s. My bad! The velocity is 1/2 cycle per second, or 1 cycle every 2s. So, this should be fine.
What do you mean by "bumping the solution"?

Re: Moco goals for average speed in cycling model
Hi everyone! I resumed the simulations recently and would like some extra help, if possible. I have the human model with 4 actuators on the joints (left and right hip and knees), and the feet are connected to the pedals of a crankset. With your help (thank you!), I've achieved the following mileston...

Re: Moco goals for average speed in cycling model
Hi Nick, that makes sense. I changed it back to control ranged from -1 to 1.
I am grateful for your assistance over the past few weeks. I'm confident to say that the issue I mentioned in this post has been successfully resolved. Thanks again! =]

Re: Moco goals for average speed in cycling model
Hey everyone! Just wanted to share a quick update on my simulation progress and give a big shout-out for your fantastic suggestions! I solved the problem of the post using the MocoStateTrackingGoal . First, I generate a sto file with time and angular speed data following a linear ramp pattern. def c...
