Data Analysis for the publication 10.1002/jbio.202000264. It is divided in three different folders describing three different part of the data analysis: A. DATA TREATMENT RAMAN (Folder 1) 1. Import data using the Import_Raman script. 2. Plot Spectra and integrate DOX band Figure 1A Figure 1B 3. PCA Figure 1D Figure 1C SM 1 4. PLS Figure 1F Figure 1E B.
