Gwyddion – Free SPM (AFM, SNOM/NSOM, STM, MFM, …) data analysis software

Gwyddion

Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for analysis of height fields obtained by scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM) and it supports many SPM data formats. However, it can also be used for general height field and image processing, for instance for analysis of profilometry data. See the overview of data processing functions.

Gwyddion is Free and Open Source software, covered by GNU General Public License. It aims to provide a modular program for 2D data processing and analysis that can be easily extended by third-party modules and scripts. Moreover, the status of free software enables to provide the source code to developers and users, which makes the further program improvement easier.

Gwyddion works on GNU/Linux, Microsoft Windows, Mac OS X and FreeBSD operating systems on common architectures, all systems can be used also for developement. Its graphical user interface is based on Gtk+ and porting to other systems supported by Gtk+ should be easy.

Current versions
Stable:2.38
gwydump:2.1
gwyiew:2.0
threshold:2.4
gwyfract:0.8

2014-09-18: A new version of the sample standalone module was released: threshold-example-2.4. It includes support for integrated help, introduced in Gwyddion 2.38, and fixes version check issues. So the sample module is still compatible with older versions of Gwyddion.

2014-09-18: Version 2.38 “Index Infiltration” was released, featuring an integrated help (sort of), a bunch of new file modules, pygwy and volume data processing improvements and more. The detailed news contain the full list.

2014-07-22: The sample standalone module, was moved to Applications, reducing the download page clutter a bit.

2014-06-27: Version 2.37 “Too Technical Tears” was released. It contains a number of mask and grain-related improvements but also a new file module, synthesis module and lots of other goodies. See the detailed news for the full list.

2014-06-13: A page with tutorials was added, including the nice set of video tutorials by Waldemar Smirnov originally published at soft-hummingbird.com.

2014-06-06: The on-line module list is now available in all languages for which a user guide translation exists. The links in language version of the list point to the documentation written in the same language.

2014-04-07: We are happy to announce the publication of a Measurement Science and Technology paper Independent analysis of mechanical data from atomic force microscopy which deals with independent volume force-distance data fitting. The integration of the methods described there to Gwyddion is underway, at least a part should appear in the following version.

2014-04-03: Download links that point to the SourceForge.net file repository were corrected to point directly to the actual files. We are sorry for the inconvenience when they were being redirected to the repository root.

2014-04-02: Version 2.36 “Casual Collider” was released. The main new features are three synthetic data modules but there was a bunch of other changes, see the detailed news for the full list.

2014-03-03: A new version of the sample standalone module, threshold-example-2.3, was released. It includes support for logging of data operations which was introduced in Gwyddion 2.35. The logging support is compiled only if a sufficiently new Gwyddion is found so the sample module is still compatible with older versions.

2014-03-02: Version 2.35 “Record Rampage” was released. See the detailed news for the full list of changes.

2013

2013-12-18: Updated MS Windows installers, denoted 2.34-1, were released to correct the crash when Gwyddion is run in Italian.

2013-12-16: A patch for version 2.34 was published, fixing a crash when Gwyddion is run in Italian. See also Patches.

2013-12-15: Version 2.34 “The Frame Fungus” was released. It brings new affine distortion correction and Otsu's thresholding modules and a number of NT-MDT improvements – among lots of other changes that are all listed in the detailed news. It also brings some toolbox tweaks, which requires the obligatory XKCD reference.

2013-12-13: A new version of the sample standalone module, threshold-example-2.2, was released. It contains updated cross-compilation instructions and some small bug fixes.

2013-11-10: Maybe you did not know that the Gwyddion toolbox can be customised and reorganised for faster access to functions you use often. Even though it has been possible for a long time, no documentation how to do it existed. But now it does.
