Scalar Vs. Wave results in OCEAN-XL

Hi there!

I have been trying for weeks now... please advice

I am running a DC sweep simulations with stepped parameter using OCEAN-XL script. Think transistor transfer characteristics...

I also have a CSV file containing data which I want to use as reference for my error calculation. Basically, after every sweep I am trying to calculate error between simulation and CSV data for each parameter value.

My problem is that in Maestro GUI everything works perfectly. By averaging my "error wave" I get scalar number, but when running OCEAN scripts (my own or generated in GUI) I get "wave" result.

How do I get scalar number from "wave" result in this case?

"calcVal" complains about cyclic dependencies, functions "leafValue", "value", "ymax", "mag" all produce wave result after running OCEAN scripts, I guess due to 'sweeps evalType.

There has to be a way how to dig up the scalar number since GUI can do it correctly.... 

Thanks you guys...
