AnyInputC3D - Time Problem

Main Forum
1

Dear AnyBody Community,
I have a problem with the AnyInputC3d-Function.
I have included a c3d-File with this function and when I reload it I get the error “Time t has an invalid value…”.
My C3D File is working with Frames, and I don’t know if this is the problem with it.
So I hope you can help me with some little tipps to get my model walking.

Thanks to you,
Anja.

Hi Anja,

You have to set tStart and tEnd in the study to fit the data of the C3D file. tStart is usualy zero, and you can calculate tEnd from the number of frame and the video frame rate of the C3D file.

Best regards, Sylvain.

Hey Anja,

I would like to add a little comment.

An easy way to see the FirstFrameNo (the first frame number), LastFrameNo (last frame number), and VideoFrameRate (the sampling frequency) in the c3d file is to simply outcomment your study and load the model. Then in the header section of the AnyInputC3D file you can find these three values from which it is possible to calculate the tStart, tEnd and nSteps in your study. When you have done that, include your study again with the updated values and it should work.

I hope that helps else write again.

Best regards
