The species-level classification accuracy using Random Forest for REIMS using electrical diathermy and ALDI-MS thermal disruption mechanisms for ten species is shown. For each species and thermal disruption mechanism, the classification accuracy score for mass ranges of 50 to 500 m/z (fatty acids and metabolites) and 600 to 1000 m/z (complex lipids) are shown. Full taxonomic names for each species abbreviation are given in the supporting information.
