Hello,

Thank you Paul, I tried your method and it worked. But offsetting the slide trouble me, and I would like to really handle the data freely. I got almost all the ingredient I needed, I just need a function that when I feed it the cell information, it give me the coordinates of points. It must be somewhere in the source code, or may be on Internet, is anyone know about it? 

Thank you very much.

But I have read somewhere that you can't mix the equally spaced value with GLL points. So in the binary file I got, what type of mapping is using? GLL abscissas or equally spaced?
