My question is, how to do waviness separation in 2D (i.e. Sq after ISO
25178)? The statistical quantities tool doesn't have this option.
At present, 2D waviness separation according to any ISO norm is not
implemented in Gwyddion.
Thank you for your fast reply. The patch works properly!

Dear Lena, excuse for my delay in answering, I think that the only way to
compare different roughness values is to use the same cut-off frequency,
indeed if the samples are similar

I'm sorry, I think we are talking of different things. I mean that
using the 'roughness tool' (ISO button) we select a cut-off value in
order to filter our data (digitalized using a DFT function as you
previously reported). This cut-off frequency value should be the inverse
of a parameter
Let's verify if I've understood:
if I have a line long 1000 nm, scanned with 256 points, then I'll have a
pixel of approximately 3,9 nm
if I choose a cut-off of 0,12 It means that I'm cutting informations
taken with a step more than 65 nm?
