Inverse kinematics omits a time frame

Post by Andrew Meyer » Fri Aug 22, 2014 1:31 pm

Hi,

I've been doing inverse kinematics analyses in opensim 3.2, and one of the time frames keeps getting omitted in every trial. I believe it is omitting the last time frame, since the new time vector in the .mot file only goes to the second to last time reported.

I am uploading the model, marker data and the ik setup file being used for the analysis. Is there something I am missing that prevents this time frame from being used?

Thank you!
Andrew

Hi Andrew,

This may be a small bug in the code when dealing with array size. Please file a bug report under the 'advanced' tab on the left.

Thanks for the message.

I realise this is quite out of date but I still seem to get this error when using the IKTool via the Matlab API in OpenSim 3.3. I haven't yet upgraded to OpenSim 4.0 (is it fixed there?). Is there a workaround?
