Processing of the ATR-FTIR and Raman spectral datasets for all categories by SPA-LDA.

(A) Twenty three wavenumbers selected by the SPA-LDA model for the ATR-FTIR spectral dataset. (B) Graph representing the power calculation used to identify the optimum number of wavelengths used for SPA. (C) Scores (DF1 × DF2 × DF3) plot calculated by SPA-LDA. (D) Seventeen wavenumbers selected by SPA-LDA model for the Raman spectral dataset. (E) Graph representing the power calculation used to identify the optimum number of wavelengths to be used for SPA. (F) Scores (DF1 × DF2 × DF3) plot calculated by SPA-LDA.
