[Gwyddion-users] Fractal dimension, cube/box counting plots

Hello, I try to plot cube/box counting plot with number of boxes over gridsize with gwyddion. So I plot them with gwyddion, export them to ascii and try to recalculate them: 1) The slope of log(N(l)) versus log(1/l) plots gives the cube counting dimension. The fractal dimension conforms to

Thank you for your fast reply. The patch works properly! Best Regards, Tobi On 04.08.2012 16:34, David Nečas (Yeti) wrote: On Thu, Aug 02, 2012 at 04:06:32PM +0200, Tobias Cordes wrote: I´m characterizing topographies by the toolbox roughness. I should divide there the roughness and waviness

[Gwyddion-users] roughness parameters, using cut-off below 0.01

Hello, I´m characterizing topographies by the toolbox roughness. I should divide there the roughness and waviness profile by a cut-off factor below 0.01. Where the cut-off is the factor of the Nyquist frequency. Is there a possibility or can please someone give me a hint where to make the
