Closely related to the metadata, the “history” of a dataset, namely the list of operations performed during processing and analysis, is of high importance.

Every dataset that gets loaded into the GUI has its own “history” and every function of the GUI that performs an operation on a given dataset creates a record in that history, including the function name, the parameters used, and the date of operation.

Once the “history browser” is implemented, this provides the user with a convenient interface to explore the complete set of operations performed on a given dataset.
