Figure 3: An example of results window from searching with a sample spectrum against a custom spectral library. The library was constructed using IC/IS MALDI mass spectra of plant pathogens from the category of downy and powdery mildews. Abbreviations: DB – database (library), FA – ferulic acid, SA –sinapinic acid. The library was challenged with a sample mass spectrum obtained by IC/IS MALDI-TOF MS of Bremialactucae spores and the obtained results finally sorted in a descending order according to the respective score values.
