Hey David, you can call me adila (and/or 'mate') :) I haven't run any RRA to be honest, but from my understanding of CMC (which I *think* uses the same algorithm for tracking), it tries to solve the following equation: ddot(dq) + kv* dot(dq) + kp * dq = 0, ...... (1) where dq is the difference betwe...

Hey David, Not sure if I'm off the mark here, but your Tasks file has: <kp> 100.0 </kp> <kv> 20.0 </kv> <ka> 1.0 </ka> for point tracking which *might* be the problem...maybe try change that to <kp> 100.0 100.0 100.0</kp> <kv> 20.0 20.0 20.0 </kv> <ka> 1.0 1.0 1.0 </ka> (...and cross your fingers) :)

Hey Ayman, I was wondering if there was a simple way for me to edit the "description" part of the output files from the ForceReporter analysis. I.e., to access the "constructDescription() part of the ForceReporter analysis class and add in additional descriptors before the "end header" portion. All ...

Hey Jesse, I was wondering if when you clicked on a user's name, their 'profile page' would also have a link to the projects they were working on as well. Or if you could link it to their https://simtk.org/my/ page. In the past, I've used that to learn a little bit more about the various projects pe...

Ah, got it Joana. If there is, i don't know of it...I know there's a way to visualize the ground reaction forces as arrows, but i don't know if something similar exists for the forces reported in the ForceReporter. Would be a nice feature though (if it doesn't already exist)...you could try requesti...

Hey Joana,

I think all you have to do is select Tools --> Plot --> Y-Quantity --> Load File --> select the .mot file you want to plot --> select whatever variables in the .mot file you want to plot.

Hope this helps,
adila

<t>Thanks Ayman, your explanation was perfect. <br/> <br/> On a similar note, does Forward Dynamics exert its forces along the model's generalized coordinates as well? <br/> and, is the ForceReporter reporting these forces (along the generalized coordinates), or some other frame of reference.<br/> <...

<t>Hey Ayman,<br/> <br/> Do you know where the ID tool exerts its forces? I'm not sure if it's at <br/> (1) the joint frames connecting the bodies that move relative to each other<br/> (2) at the CMs of the individual bodies that are connected by a joint<br/> (3) at the origins of the body frames<br...

<t>hey Ayman,<br/> <br/> Thanks for the quick reply. I tried what you said -- e.g. cout<< "X_FM is" << X_FM <<endl; -- rebuild, reinstall, rerun, but nothing is printing to screen. I'm seeing this message though which I don't think was there before:<br/> <br/> WARNING: UNSUPPORTED Trying to load a f...

<t>Hi,<br/> I was wondering if there's a simple syntax for printing something to the 'messages' screen of the OpenSim GUI. I'm writing a plugin and just want to be able to see the function outputs (e.g. positions, rotations, etc) as I run things for error checking (without having to print them to an...
