![]() ![]() NeXus is built on top of the scientific data format HDF5 and adds domain-specific rules for organizing data within HDF5 files in addition to a dictionary of well-defined domain-specific field names. It is being developed as an international standard by scientists and programmers representing major scientific facilities in order to facilitate greater cooperation in the analysis and visualization of neutron, x-ray, and muon data. nex) is a common data format for neutron, x-ray and muon science. ![]() See the documentation for more information, as well as a video on using HDF5 files via HDFView, which is a visual tool for exploring and editing HDF4 and HDF5 files. HDF5 also supports many programming languages such as Fortran, Python, R. Many common software tools used for academic research support HDF5, including Labview, MATLAB, Mathematica, ParaView et Matplotlib. The HDF5 format also allows for embedding of metadata making it self-describing. HDF5 uses a “file directory” like structure that allows you to organize data within the file in many different structured ways, as you might do with files on your computer. Originally developed at the National Center for Supercomputing Applications, it is supported by HDF, a non-profit corporation whose mission is to ensure the development of HDF5 technologies and the accessibility of data stored in HDF. hdf5) is a format designed for extremely large, complex and heterogeneous data, notably used in physics, astronomy, earth sciences, engineering, genomics and computational fluid dynamics. The use of open formats is one way to make scientific data ‘Findable, Accessible, Interoperable and Reusable’.īelow we have provided a non-exhaustive list of open standard formats used in the field of physics. Currently, the UGRID Reader supports 2D unstructured triangular, quadrilateral and mixed triangle/quadrilateral meshes, while the data can be defined per cell or per vertex.Accueil Best practices Establishing a data management plan Standard formats in physics The UGRID Conventions extend the CF-conventions with topology specifications and are increasingly popular with an important subset of the CF community, so that they warrant the development of a customized reader.įor visualization purposes with ParaView, this translates into a customized plugin that enables the reading and rendering of UGRID meshes stored in the NetCDF file format. In this context, the UGRID reader plugin implements the UGRID conventions, a proposal by the UGRID Interoperability group for storing unstructured model data in NetCDF files. is it a one dimensional network, a 2D triangular mesh or a flexible mixed triangle/quadrilateral mesh, a 2D mesh with vertical layers, or a fully unstructured 3D mesh. ![]() However, it is often necessary to have additional information about the topology of the underlying unstructured mesh, i.e. The CF-conventions allow storing unstructured data defined at a series of points. We developed a visualization component in collaboration with the "Numerical Methods in Geosciences" group.
