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
I am unable to drag data into a single graph in the 2.23 version. Is there a
fix for this or should I go back to 2.22? Thank you.

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?
