Gwyddion is a free evaluation software for raw data from many atomic force and scanning tunneling microscopes . (The name comes from a wizard from the Celtic mythology of Wales, see Gwydyon .) Among other things, due to its license status, it is widely used in science, research, teaching and education.

Availability

The program is distributed as free software , including the source code, under the terms of the GNU General Public License (GPL). Many Unix-like and Windows operating systems are officially supported . In the popular Linux distribution Ubuntu , it can be installed directly from the standard package sources. It is currently the only open source solution for RKM data analysis in active development.

Functionality

Gwyddion is used to analyze elevation fields and other two-dimensional raster data. While it is primarily used for data from various types of scanning probe microscopy (such as RKM , MKM , RTM , SNOM / NSOM ), it can also be used, for example, for the analysis of profilometric data.

It reads over 50 different file formats, and it is saved in its own file format ( .gwy) with double precision . The software can, among other things, filter the raster data (for example high-pass filtering to normalize the height fields) and maximize contrasts, render them as a three-dimensional extruded and shaded area and display the image data using a ( false ) color palette by applying the depth scale to one of the The color gradient created in the palette. Furthermore, by breaking them down into foreground and background using various segmentation techniques, particles can be extracted and automatically recognized, counted and measured. With the help of the Fourier transformation , for example, certain repeating patterns can be extracted.

The software can also be integrated as a module via Python 2 and thus allows access to Gwyddion functions.

development

The software is for many years mainly by David Nečas ( "Yeti") and Petr Klapetek by the Czech Metrological Institute ( Český Metrologický institute developed CMI). Version 1.0 was released on March 10, 2004, and version 2.0 on September 30, 2006. It is programmed in C and has a GTK + -based graphical user interface .
