A dataset not only consists of a “list” of numbers that represent the actual data, but as well, and not less important, of a list of additional information, including, but not restricted to, the measurement setup used, the typical device parameters, details about the sample, …

Different groups/people developed different stategies to save these important data (throughout “metadata”) together with the pure data.

The trEPR toolbox and GUI help both to collect all these metadata and to provide the user with a convenient interface to access and modify them.

As the GUI save function saves the complete dataset record with its full structure to an XML file (compressed in a ZIP container), it retains the full information provided for a single dataset.
