Re: ID algorithm

Thank you for making it more clear.

So that's why OpenSim is able to compute a solution even if there is a lack of some external forces (at the opposite side of the dynamic chain for example)

ID algorithm

Dear all Does anyone know what algortim is implemented into OpenSim 3.3 for Inverse Dynamics ? Actually,OpenSim Documentation on confluence website [1] suggests that the algoritm is based on a global optimization, described in the Kuo's paper [2] But theoretical manual of SimBody(I have the 2013 ver...

Re: frame definition in OpenSim

As I am changing tem, I was looking for a way to confirm my frames directly in OpenSim interface and not only the drawings of the bodies axis.

But you are right I should continue to base my reflexion on the model directly

Re: xml_writeOSIM.m

Apparently, there is a problem with the matlab function in the 2014b version.

That problem can be solved by changing the xmlwrite_xerces code by simply changing
set(objOutputFormat,'Indenting','on');
by
set(objOutputFormat,'Indenting',1);

xml_writeOSIM.m

Hi everyone I am modifying an OpenSim model through Matlab pipeline. So I read the existing model, change some information in the structure (basically the relative locations of bodies,...) and I would like to write the new xml. However, the xml_writeOSIM is not working... I am using Matlab R2014b an...

frame definition in OpenSim

Dear all

Is there any possibility in OpenSim for finding the frame definition of the joint or bodies?
Or the unique possibility is to recreate them from the informations of confluence website?

Thank you

Re: IK - report_marker_locations

Do you know how to define the name of the file created with the flag ?
<report_marker_locations> true </report_marker_locations>

Re: Inverse Dynamics forces header

You are right, that was one of my errors ...

Do you know how OpenSim deals with the different time vectors ?
How does it work if the movement analysis time vector and the force plate time vector are different? (e.g. frequency and spacial offset)
