    After I upgraded PLS_Toolbox, my scripts which used MCR no longer work.

Possible Solutions:

    In version 3.5 of PLS_Toolbox, the function formerly called mcr was renamed to als. The Multivariate Curve Resolution (MCR) code was expanded to output a PLS_Toolbox standard model structure and to allow more standard inputs.

    You have two options to make your code compatible with this change

      (a) rename all calls to the function mcr() to call als(). The I/O for the new als function is fully compatible with the old mcr function.


      (b) revise your scripts to use the new I/O of the mcr() function. This also makes your scripts more compatible with other PLS_Toolbox features such as plotting of scores and loadings and application of models to new data.
