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.
minor feature: Support for Asylum Research Ergo HDF5 and several 3D geometry formats was added. A new tool enables quick autocorrelation length estimation. Support for Nanoscope, WSxM, WSF, Olympus OIR, DM3 DM4, GDEF, VTK and raw XYZ data was improved. There were miscellaneous small bug fixes and improvements, mainly in statistics-related functions.
