Description
Electron microscopes come in many flavours, with instruments ranging from table-top scanning electron microscopes to 4 or more meters tall (scanning) transmission electron microscopes with hundreds of electron optical elements in them. Likewise, the type of data they produce is very diverse, ranging from spectra to diffraction patterns and images, and 3D, 4D, 5D, or higher dimensional hypercubes of data, which are stored in different proprietary formats, depending on the instrument vendor. In this presentation I will introduce the NOMAD-Oasis setup we run within the structure research and electron microscopy group at the physics department of HU Berlin. I will highlight the pynxtools-em software which allows us to convert data from different vendors to an open data standard, which NOMAD is able to display, independent of the dimensionality of the data. I will also show how the NOMAD Remote Tools Hub (NORTH) is utilized to perform complex data processing tasks of data sets being several tens of GB in size, and incorporating high-performance computing, directly on the server – including tools which can be controlled using natural language.
