<t>Hi Rahul-After IK, are you plotting something from the *_walk_ik.mot file? If so, the values you see are the joint coordinates/angles computed by IK. After ID, if you plot something from the *_force.sto file, you are plotting torques/moments. You are correct in your understanding that the muscle ...

I was wondering if there were any changes to the way the CMC tool works in version 1.8.1. When I constrain a particular muscle activation in 1.8.1, CMC doesn't seem to respond to the constraint at all. It responded well in 1.5. Any ideas?

<t>I wouldn't be concerned except this started happening when I tried to reproduce some data I produced yesterday. I made a copy of a folder and literally re-ran all the same files and got a different output, which should never happen. I diffed all the input files and they are exactly the same in ye...

<t>I am trying to open a generic model (Gait2392) that I have used many times before. I have not modified it. But suddenly today when I try to use this same file, I get the following: <br/> <br/> ERROR: In C:\eran\dev\VTK\Filtering\vtkDemandDrivenPipeline.cxx, line 710<br/> vtkStreamingDemandDrivenP...

<t>I'm curious how many people run IK using joint coordinate data and how many use just marker data. <br/> <br/> When I use joint coordinate data w/marker data, everything tracks great. When I use JUST marker data, my IK output is off by as much as 7 or 8 degrees at times, no matter how I adjust wei...

<t>After I run RRA, my states file contains results that appear valid. (The dorsi-plantarflexion simulated matched real values from lab). After I run CMC, however, this becomes extremely skewed and when plotted, simply looks like noise. However, the other values in my post-CMC states file(fiber leng...

<t>I've been using the gait 2392 model, which seems to have a "default" weight of I think 75kg. I have noticed that when I scale subjects close in weight, everything turns out better. When I scale much lighter subjects(ie 28kg), things tend to be very messy. I thought this might be because the inert...

<t>I was wondering what kind of configuration/system setup people are using. Processor, hardware, etc.<br/> <br/> It takes me hours(2-4 hrs usually) to run one pass of CMC (and sometimes RRA). I can't imagine this is the case for everyone out there. Are there system requirements/configurations that ...

<t>Yes. In version 1.5.5 (and older) if I locked a coordinate, I would get a message saying "Coordinate.setValue: WARN- coordinate subtalar_angle_l is locked. Unable to change its value." And you would get that message just once, and then Scale or IK or whatever task would proceed. Now, I'm getting ...

<t>I've found that when I scale a model in say version 1.8, I can't open it in version 1.5.5.<br/> I get a message saying "Model_SCALED.osim contains OpenSimDocument, expecting Model". (It does open up again in version 1.8, so it seems to be saving ok.)<br/> <br/> Is this intentional, or should I be...
