Virtual markers data

[Maha Abbassi]

Hello,

I want to compare the trajectories of the experimental markers and the virtual ones, But I don't find the virtual markers data (the data saved in the motion file after doing the inverse kinematiks task does contain the experimental markers data).
Can anyone please tell me what to do to get it?

Thank you!

Hi

Two options,

1:If you want them writen to a file, include the xml tag
<include_markers>true</include_markers>
under the IKTrail tag in the xml

2: If you want to view the error, look at the project https://simtk.org/home/visutoolopensim/
There is an option to view your marker error in the model. Check out the manual/example, and if you have any question just shoot a message.
(for this you do not have to include the xml tag)
cheers

Ok, thank you Anders.

I tried your first suggestion, it worked.
I'm trying to use the other tool now because it seems quite interesting.
