It seems that one of the multiplication signs got cut off during copy/pasting, so the equation was incomplete, and that was the issue with "function_2" message. Found out a day later when looking over the equations. Sorry to have brought it up prematurely. Regards Mikhail Solovyev On Mon, Feb 6, 2017 at 1:00 PM, wrote:

Hello to all.

I am encountering an issue when trying to input a trigonometric function in my GDS window. When trying to fit the data, i get what appears to be an error

GDS: 'FeN0' function_2

And it applies to every GDS that has the trig function in it. What exactly does the function_2 mean?

Thank you.
