how to do the spectral analysis was created by richor
Dear all:

I want to get the bending modulus of the membrane,but I cannot find a easy way.
I have extracted the coordinates of all PO4 at the last frame,but how could I do the
Fourier analysis for such a discrete and irregular array?

I would be very appreciate if anyone can give me a clue.

I'm not sure if this is the right place to ask this question, since it is not really Martini related. Besides, I also don't know the answer, but maybe papers from Edholm might help. For example: Interpretation of Fluctuation Spectra in Lipid Bilayer Simulations, Erik G. Brandt, Anthony R. Braun, Jonathan N. Sachs, John F. Nagle, and Olle Edholm
