Electron back scatter diffraction (EBSD) via MTex

MTex is a software for texture analysis written in MATLAB. The software is one of the key tools of materials engineers and geologists to perform computations in orientation space to segment a characterized portion of material into a representation of its microstructure. The software offers the largest and most mature solution for analyzing and plotting texture analyses solving research questions about texture quantification and visualization using pole figures, orientation distribution functions, inverse pole figures, and grain-boundary-network characterization. Thanks to its support of all symmetry classes, the tool has not only found a wide acceptance within the field of materials engineering but is also vividly used in within the geoscience communities.

Computational results from MTex are most frequently preserved via MATLAB .mat files or using ad hoc reporting with text files and other binary containers with custom formatting. For pynxtools-em we explored an alternative strategy of automatically converting MTex class objects to a standardized NeXus-based HDF5 file representation. To connect these HDF5 files to the pynxtools ecosystem and upload these for instance in NOMAD, a parser was generated.
