Hi, I am a new user to anybody and have been working through the tutorials. I have got up to the 'Building Block' tutorial, to construct a pedal model. At the...
Hi Simon Welcome to the group Please let us know which version of the AnyBody system and the repository you are using, this will facilitate solving your...
I was looking at Sunwook's sway model that is driven by Vicon, and I am trying to do the same, however I have a question regarding the Initial Conditions data....
What does the error message "Parameters values are not monotonically increasing" mean when I am trying to run a model from motion capture data? The problem...
Hi Sarah, It means that the time values in the driver are not monotonically increasing, i.e. every new time must be strictly larger than the previous one....
Hi Simon The problem should be solved now. The the new version 2.0 has a more strict error check on the AnyScript than the previous versions, and it found the...
Dear Every Body, My model is composed by 4 segments: pelvis, thigh, shank and foot. each of them are driven by 6 drivers. there is no joint in my model. my...
Hello Lola, It is hard to say precisely what is wrong with your model without looking closer at the details. However, from your description it does sound like...
Thank you for your answer. Have you got any idea on how i could try to go round this problem? i suddenly have two idea in mind: first: do you think that if i...
Hi Lola ... You should add exactly the reactions that the usual joints provide. - At least this is the case if you want the model to resemble a real leg. If...

Hello Simon, You are quite right about the webcast. Here are some links to various supportive information related to the event. Please notice that yahoo may...
Hi I was just wondering if it is possible to introduce markers on an upper body model specifically around the shoulder, so that co- ordinates from a motion...
Hi Simon, Sure you can. This is the procedure: 1. Define an AnyRefNode at the segment you wish to drive and at the position on the segment where the optical...
