Re: Scripting in Matlab for Scaling of Model
Hi Ayman, Thanks very much for the quick response (I know you get a lot of queries). Can you provide me both instances of the syntax? I will only need to point to the trc file for scaling the bodies (measurements), but I'm interested in learning how to use scripting more generally so I can extend my...

Re: Not Obtaining New Mass Distribution When Scaling
Hey,
May be a bug. Are you in v3.0 or the beta?
Either way, you can load the Osim model into a Mat structure and edit the inertia manually or through a function. A bit annoying though.

Scripting in Matlab for Scaling of Model
Hello, I'm using v.3.0.1 and attempting to using Scripting + Matlab to run a scaling process within a larger Matlab data processing pipeline. Reason for scripting instead of xml creation/editing: xml parsing in Matlab creates problems in OpenSim. I used the example 'setupAndRunIKBatchExample.m' as a...

Re: Using matlab to read message window results
Hi Maria Isabel Orselli, Thanks for writing me back! It has been while since I was dealing with this issue. We are writing some quality control programs to handle large numbers of trials, and we want to flag errors using the log file. Your suggestion works great. Do you know if there is a way to hav...

anatomical landmarks in .vtp/ SIMM bones
Hi All, I have a few questions about the bone files used in OpenSim. 1) Taking Hamner's model as example, are the bone files used in the lower body the same as SIMM bones? I realize they are different file formats, but is the data the same? 2) How are the origin and coordinate system defined in a bo...

Using matlab to read message window results
Hi All, I was wondering if the reporting in the message window during OpenSim tool execution can be accessed by Matlab directly or otherwise? I am particularly interested in the marker error during scaling and IK. Is there any way to get OpenSim to print these to some location or for Matlab to read ...

Re: sample code for printing to Messages screen
Hi Guys, This may be slightly different, but we are planning to batch process a bunch of trials and wanted to use the residuals from the IK process as a metric, i.e total error or marker specific errors above some threshold gets flagged. Is it possible to access the message window results from vario...

Re: Multiple Joints between two bodies
Hi All,
I believe the Analyze --> Joint Reaction tool will permit this analysis? Can we also output moment arms relative to these points?

Multiple Joints between two bodies
Hi All, I want to sum the moments about the medial and lateral condyles of the tibia during various gait tasks. Is there an established OpenSim way to do this? (in fact I also need to output the muscle moment arms with respect to these points as well). Our current OpenSim model has a 3 dof knee with...
