Composite correlation index (CCI) heat map grid of mass spectrum protein profiles, database 1, n = 60. Levels of mass spectral reproducibility are indicated in blue and red, revealing incongruence and relatedness between spectra, with a correlation index variation between 0 and 1, respectively. The coloured squares of the central diagonal reflect the degree of reproducibility of each mass spectrum when compared to itself. Around the central diagonal, spectra from various specimens of the same species were compared as well as spectra from different species. The CCI matrix was calculated using MALDI Biotyper v4.1 software with default settings
