Gwyddion

Gwyddion is a modular SPM (Scanning Probe Microsope) data visualization and analysis tool. It can be used for all most frequently used data processing operations including: leveling, false color plotting, shading, filtering, denoising, data editing, integral transforms, grain analysis, profile extraction, fractal analysis, and many more. The program is primarily focused on SPM data analysis (e.g. data obtained from AFM, STM, NSOM, and similar microscopes). However, it can also be used for analyzing SEM (scaning electron microscopy) data or any other 2D data.

Release Notes: Three new file modules have been added: NanoScanTech NSTDAT files, FEI Tecnai imaging and analysis SER files, and Digital Micrograph DM3 TEM images. Four new data processing modules have been added: simple simulation of PID loop effects during scanning, simulation of lateral force from the topography channel, neural network data processing, and XY data denoising based on horizontal and vertical scans. A Gnome3 thumbnailer is now installed for automated thumbnails of SPM files in Nautilus.

Release Notes: File import modules were added for old NT-MDT MDA and NanoObserver. Images in the "Image list" section are now loaded from Nanoscope files. Pixmap export permits changing the font of the labels. It is now possible to preserve RMS in 2D FFT. Compatibility with GLib 2.32 was corrected.

Release Notes: The 3D view can now use different data for surface and texture (overlay mode) and display a false color scale, keyboard shortcuts are configurable, and data previewed in the "file open" dialogue can be plane- or row-levelled. Six new file modules were added: Code V INT, Zeiss SEM, Hitachi S-3700 and S-4800 SEM, Alicona Imaging Al3D, ISO 28600:2011 SPM data transfer format, and WITec ASCII export.

Release Notes: New file import modules were added for Benyuan CSM, WITec project, Raster Data (NRRD), Automation and Robotics Dual Lens Mapped data, old Gwyddion dumb dump format, OpenEXR, 16bit PNG, PGM and TIFF images and Ambios AMB (experimental). OpenEXR and NRRD can be also exported. Many other file modules were improved. The line noise synthesis module was reinstated. Spanish translation has started, all translations were updated.

  •  08 Apr 2011 22:01

Release Notes: This is mostly a bugfix release, improving the import of Nanoeducator, OPD, NT-MDT, and Attocube files and adding some support for MUL files. There were also miscellaneous bugfixes and small user interface improvements. The Czech, French, German, Italian, and Russian translations were updated.
