I can reproduce it (it's a unintended effect of keeping the selection)
and will fix it.

Gwyddion 2.24 was released, however, the known issues listed at

    http://gwyddion.net/switch-to-mingw32.php

remain unfixed in this version.

While DnD works nicely in Gtk+ 2.16, just replacing the bundled Gtk+ led
to different compatibility problems (such as icons not displaying in the
Gwyddion toolbox, i.e. also unacceptable) when I tried this.

I think it is possible to build Gwyddion for MS Windows and pack it with
the right set of DLLs in such a way that everything works.

[rant]
On the other hand, I do not think attempting this is a good use of my
time and resources.

And do you feel comfortable with MS Windows packages being created by
someone who has never worked with the latest two incarnations of this
operating system (and only works with the previous because the control
software of some instruments runs on it) or whose idea of testing is
running it under Wine?

The installation of gwyddion with pygwy on OS X is not too simple,
but also not too hard:

a) install "python_select":
	sudo port install python_select

b) set you macports python version to the default version
	(python2.7 in my case):
	sudo python_select python27

c) install "py-gtk2":
	sudo port install py-gtk2

c)2) is you want syntax-highlighting:
	sudo port install gtksourceview2

d) configure and build gwyddion again.

This _should_ work - please give a comment if this does
not work as expected.

Yes, and not only of pygwy on OS X: screenshots from year 2006 still can
give an idea how Gwyddion UI looks like but...

Importing a tip model

Hello all,

New to this mailing list and Gwyddion but did some searches and
hopefully it will not entirely be a silly question.

I'm looking into blind reconstruction (had a look through
Villarrubia's paper) and I wanted to something similar as Fig.6 but
instead of topography we would be looking at potential, thermal and
other.

So I thought what could be a good starting point is to make up an
ideal sample and an ideal tip and convolute them with Gwyddion.

I'm fairly sure I can do some ideal sample in some  way  but I'm
having trouble with the tip. I'm working with gwydump to find out the
structure of the gwy file: if I find the data for a tip I think I
would know how to get it out.

But how to I put in a tip model made up by myself? In a gwy file or
any other file that gwyddion reads? How would it recognize it as a
tip?

I tried importing a previously generated tip (by gwyddion) from a txt
file but I must have missed some parameters. And if I managed to
import the file would gwyddion recognize it as a tip?

Thanks for your time and Gwyddion!

Generally, trying to read GWY files with software not using Gwyddion
libraries is difficult.  However, you can export the tip data as a plain
text file that is much easier to read (or GSF).

In any file Gwyddion can read.  It will not recognise it specifically as
a tip; any image can be used as a tip in the tip operations if it is the
same physical quantity (including lateral dimensions) and reasonably
smaller, this is taken as at most 1/4 of the surface size.  Of course,
it should also have the same pixel size but it can be resampled.

Yeti

Potential Z scale issue

Hi

I'm running Surface Potential measurement with a DI Multimode.
While opening the potential channel with the newly installed 2.24 Gwyddion, the Z scale shows V^2 rather than V. Also, when compared to the values in WSxM, the values in Gwyddion  are about 10 times smaller.

I've re-opened an older file I have, and this one gives the same scale and values  for both Gwyddion and WSxM, as one would expect.

I would appreciate any comments.

Sincerely

Alon

V² is indeed strange.  But, as usual, it is difficult to say anything
conclusive without seeing the problematic file.  If you send it to me
please compress it.

Were the old data measured using the same instrument and software or has
anything changed?

Yeti
