touchstone files with lots of comment lines

Hi

I receive touchstone s-parameter files with lots of comment lines mixed with data lines.
The problem is these comment lines don't comply to the touchstone standard (all comments must be in the header), and my free viewer is unable to display them. After manually removing the comments it works. The files come out of Ansoft tools, I think Ansoft Designer or Nexxim.
Is there an option in Ansoft tools to not fill the files with comments? Or is there a free tool to remove them?

Was ur touchstone file not working with those commented lines ?

As I said: "my free viewer is unable to display them".
After removing the comments it displays it fine.
