Calculation of FPCA scores FDE

[#1]

How do I get in the FDE the formula columns for calculating FPCA scores? I have a NIR spectra training set with scores on 4 FPCA eigenfuctions and a GLS model predicting very well a quality parameter. How do I compute the scores from new spectra projected in the eigenfuction space of the training set? I would like to construct multivariate control charts with new scores?
