HyperSpy is an open source Python library which provides tools to facilitate the interactive data analysis of multidimensional datasets that can be described as multidimensional arrays of a given signal (e.g. a 2D array of spectra a.k.a spectrum image).
Hyperpsy aims at making it easy and natural to apply analytical procedures that operate on an individual signal to multidimensional arrays, as well as providing easy access to analytical tools that exploit the multidimensionality of the dataset.
Its modular structure makes it easy to add features to analyze different kinds of signals. Currently there are specialized tools to analyze electron energy-loss spectroscopy (EELS) and energy dispersive X-rays (EDX) data.
HyperSpy is released under the GPL v3 license.
