GCVspline Error

Post by Kathleen Reilly » Fri Oct 31, 2008 10:58 am

After successfully running IK, I get the following message when trying to run ID:
Exception:
ERROR - Evaluating GCVSpline at 1.6658 outside its domain [-0.5, 1.66204]

What is this referring to? Where is it getting these domain values from?

Thanks

Hi Kathleen,

I think we have determined that this an issue with the filter. Because of the particular filtering algorithm we use (FIR), the data is "padded" in order to have enough data points to run the filter. For now, try running ID without using the filter and see if you get a result. We are currently working on adding more robust filters (Woltring), so this will be resolved in a later release.

Hi Samuel,

I'm getting a similar error (see below) when trying to run forward dynamics. The same error occurs when the filtering process is either on or off. Any suggestions?

Thanks in advance,

Nils
