[ESPResSo] mbtools-fluctuations-bending modulus

[martina pannuzzo]

Dear all,
i need a clarification about the example fitting gnuplot script in the
file fluctuation.tcl in the mbtools package.
The k that you are calculating is the bending modulus ( express in
units epslon)?  When i try to calculate the bending modulus plotting
1/q^-4 vs <|h(q)|^2> (of the power-dat file)  i obtain a constant that
i moltiplicate for L^2, but i obtain a k value  different and
completly wrong. Please, can anyone help me?
thanks in advance.
