Howdy!
Thanks for posting in our forums! I have a couple questions for you to help clarify this issue as we continue,
1. Is the model you're working with discrete or continous?
2. What version of SignalExpress software are you using?
3. Is there a particular reason why you're using SignalExpress instead of LabVIEW for your testing?
Im wondering if this error relates specifically to the settings for the inital model step in Signalexpress and whether it matches with your model type.
