Hi,
I am working with the surface reconstruction tool of Gwyddion. From one
image, I set a model tip (a cone with 70 degrees in slope and 8 nm of
radius) and then I apply the reconstruction tool. What I do not
understand is that the reconstructed image has a lower roughness than
the measured
OK, thanks, Yeti.
regards,
Luis

Hi Erika,
I guess a possible solution is to crop the image around the specific
pit you want to follow (without re-scaling, that is keeping the sampling
resolution) and then perform the analysis on this specific area.It is
time consuming but it is a way to do it.
Hope it helps.

Hi,
I am interested in performing on a masked image some analysis by using
the "calculate 1D statistical functions" tool (for instance ACF). I want
to do it only on the masked regions. In principle, it seems that the
tool allows it as at the left bottom of the window appears the "Masking
You have to use this expression for Iec in order to get microamperes:
10^(d1-7)
where d1 is the Iec image.

Hi, Christian,
you just have to click on apply and on this graph you click with right
button of the mouse, choose export text and then you can read this file
with any graph program. Either, you can after making apply, click on
the bottom left icon (measure distances in graph) and then measure
Dear Judy,
I do not know about the parameters you are asking about, however, I just
wanted to note you that you should be aware of tip convolution effects
in AFM measurements. I do not know the size of your particles and the
tip dimensions but, in principle, the height of the particle would
Dear Lena,
I am a Gwyddion and AFM user, I will try to answer as far as I know:
1. I read: to calculate the rougness and
waviness data I need to filter the AFM-Data
first. So my question: In gwyddion when I use
the roughness parameters application, do I first
have to filter the
Dear Yeti,
it seems that the option subtract in 2D FFT filtering does not
work. In previous versions of Gwyddion I had also problems (the
filtered image was totally black when the subtract option was
applied) and in 2.23 it even does not draw the box in order to
subtract it (the add option
