The toolbox is freeware and may be used (but not modified) if proper reference is given to the authors. Preferably refer to:
Ballabio D, Consonni V, Todeschini R. (2007)
Classification of multiway analytical data based on MOLMAP approach.
Analytica Chimica Acta (2007), 605, 134-146
In short, no guarantees, whatsoever, are given for the quality of this toolbox or for the consequences of its use. It is inevitable that there will be some bugs, but we have tried to test the algorithms thoroughly.
