Gwyddion 2.47

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.

Recent Releases

2.4718 Nov 2016 12:03 major bugfix: Selections broken in several modules in previous version were fixed. There was a major overhaul of pygwy (Python scripting), including some Python API changes as well as miscellaneous improvements in image export, statistical functions tool, object and lattice synthesis, NMM import, tip modelling and Laplace interpolation. A new graph module was added, transformation to logscale.
2.4614 Oct 2016 11:10 major feature: Geometrical shape fitting (both images and XYZ), grain marking by logistic regression and XYZ data levelling modules were added as well as two new file modules, Dektak XML and Dimension 3100D. The toolbox is now editable within the program. The sphere fitting module was removed. Several modules were considerably improved: cross-correlation, row/column statistics tool, image export and data rotation.
2.4526 Apr 2016 17:16 major feature: Initial native XYZ data support was implemented. XYZ files are loaded as native and rasterized upon request. Spline selections were added, with new Straighten Path module for extracting data along a curve. All data types have previews in the data browser and file open dialogue. Experimental support for IntelliWave ESD format was added; NMM, RHK, WSxM, Nanoscantech, GXYZF, APE DAX, Seiko and OME TIFF support was improved.
2.4411 Jan 2016 14:26 minor bugfix: File import support for Leica LIF CLSM, Nano Measuring Machine and Digital Micrograph DM4 was added. Support for APE, JEOL, Keyence, Magellan, Molecular Imaging, NanoScanTech, Nanoscope, Renishaw and RHK SM4 files was improved, as well as XYZ data import. A new module visualises entropy calculation. The 3D view is always full-resolution now. A large number of various bugs were fixed.
2.4325 Nov 2015 17:11 minor feature: Sensofar PLUx and Princeton SPE file import modules were added. Function for morphological operations were added to the libraries, leading to addition of two new modules: morphological operations with masks and marking of local outliers. Several filters were added to the Filter tool and it can act only on the masked/unmasked area now. Several mask creation functions can combine the result with an existing mask using logical operations. There were improvements in raw, Nanoscantech, NT-MDT, CSM, Nanoscope, Omicron flat and GWYXYZF file loading.
2.4207 Oct 2015 08:13 minor feature: The motley collection of line correction functions was replaced with a new module Align Rows. Support for Keyence VK4 files was added and substantially improved for Omicron Flat Files. There are two new data processing modules, lattice measurement and mask distribution to other channels, and volume data modules, line summarization and Z-calibration management. The profile tool can now extract radial profiles. Volume data Cut and Slice can extract multiple items simultaneously. There was a large number of small improvements and bug fixes.
2.4126 May 2015 14:51 minor feature: Four new modules were added: graph curve alignment, volume data slicing, log-phi PSDF and ballistic deposition simulation. Most graphing function permit choosing the target graph. Multidata functions recall previously selected secondary data. Support for Renishaw, Zeiss, Nanonis and Nanonics file formats was improved. There were a number of small improvements and bug fixes.
2.4007 Feb 2015 22:08 minor feature: New modules were added for XYZ file export, automated base levelling, K-medians clustering of volume data and simple SEM image simulation. 3D view can completely exclude masked areas. A function for mask thinning and two new fitting functions were added. Mask merging can automatically mask or crop outside pixels. A number of bugs in the new image export were fixed. Several file modules were updated and/or improved: APE DAX and APDT, NetCDF, NRRD, Omicron, Nanoeducator, Raw XYZ, WITec Project, NanoObserver, NanoScanTech, OpenGPS and SPMx.
2.3914 Nov 2014 16:27 major feature: Four new file import modules were added: Renishaw, NX II, Femtoscan and ACT SPMx. Image export was rewritten and allows rendering to vector graphics formats: PDF, EPS and SVG. Fractional Brownian motion artificial surface generator was added. A crash in statistical quantities when saving the table to file was fixed along with several other bugs in 3D view, file import and other areas. Korean translation was started; Czech, French and Russian translations were updated.
2.3818 Sep 2014 11:00 major feature: An integrated help was added. File import modules for OpenGPS, JEOL JSPM, FITS and FemtoScan TXT were added as well as new modules for K-means clustering for volume data and diffusion limited aggregation (DLA) data synthesis. There were various improvements to pygwy, volume data processing and other modules. Czech, French, German, Russian and Spanish translations were updated.
