Hi, What software are you using to analyse the data? There are frameworks for Mathematica (simulationtools.org) and Python (https://bitbucket.org/DrWhat/pycactuset). If you want visualisation rather than more in-depth analysis, then you could try VisIt, which has a reader for ET data. See https://docs.einsteintoolkit.org/et-docs/Analysis_and_post-processing for a list of analysis tools that we know about. If you want to do it manually (and I wouldn't recommend reinventing the wheel), all the information you need to place the individual component in coordinate space is listed in attributes of the datasets. Look at the "origin" attribute for the coordinates of the origin of the component, and the "delta" attribute for the grid spacing. -- Ian Hinder https://ianhinder.net
