Thanks for responding, Ben. I used loadtxt() and I'm still getting a very strange looking contour plot. I've attached it and maybe that will be helpful in diagnosing what is wrong with it.

I have no reason to believe that the data itself is bad since I was making contours in IDL with the same set. 

Thank you.

When I see graphing artifacts like that, the usual suspect is that the X and Y coordinates are mixed up or something to that effect.  Could you please post some code?
