Fig. 9From: Multivariate unmixing approaches on Raman images of plant cell walls: new insights or overinterpretation of results?Comparison of multivariate methods on raw Raman data of Arabidopsis. The endmember spectra were baseline corrected and each endmember group was normalised against the most intense band (EM1: 1600, EM2: 1600, EM3: 1095, EM4: 1122 and EM5: 1458 cm−1) except for the EM6 due to the lack of a common most intense bandBack to article page
